Meghan Markle's lavish $300,000 New York baby shower appears to have come to an end, with guests including Amal Clooney, Gayle King, and Jessica Mulroney seen making their way home after enjoying the intimate celebration, which took place in a $75,000-a-night penthouse at a swanky Manhattan hotel.

And it seems as though the no-expenses-spared event went off without a hitch - at least if Amal's beaming smile was anything to go by.

The 41-year-old human rights lawyer was pictured grinning from ear-to-ear as she made her way out of The Mark hotel on New York's Upper East Side, after spending several hours celebrating Meghan's unborn baby alongside co-hosts Serena Williams and Jessica Mulroney, as well as VIPs including TV anchor Gayle King and designer Misha Nonoo.

Amal lead the charge of departures, which began around five hours after Meghan's high-profile guests were seen arriving at the hotel for the event, which is believed to have been the main reason for the duchess's surprise five-night trip to the Big Apple - her first since she wed Prince Harry in May 2018.

Off she goes! Amal Clooney was pictured with a wide smile on her face as she left Meghan Markle's baby shower, which was co-hosted by Serena Williams and Jessica Mulroney in a $75,000-a-night penthouse suite at The Mark hotel in New York City

Success? The event appears to have gone off without a hitch, at least if the wide smile on 41-year-old Amal's face was anything to go by

Into the wide world: Guests, including human rights lawyer Amal, who looked incredibly chic in a bright red jumpsuit, were seen leaving the venue shortly before 5pm, having spent around five hours at the lavish event

Lady in red: After leaving The Mark (left), Amal made her way back to The Carlyle (right), an equally luxury hotel that is located less than a block away from the venue of Meghan's shower

Perking up: CBS anchor Gayle King, 64, flashed a quick smile at the cameras as she made her way out of the hotel

Off she goes: Gayle, who was arguably the most surprising guest at the baby shower, looked slightly bemused as she made her way out of the shower, wearing a bright purple coat and a pink-and-purple furry scarf

Heading home: The TV personality, who is thought to have been introduced to Meghan by mutual friend Oprah, wore a pair of chic pale pink heels that matched her pink-and-purple outfit, which some saw as a hint about Meghan's baby's gender

Under cover: Meghan's unofficial stylist Jessica Mulroney, 37, chose to be escorted out of the hotel by a member of staff who kindly held an umbrella over her head to protect her from the snow

The glamorous fashion star brought some bold color to a snowy and gray New York day by wearing a scarlet Sergio Hudson jumpsuit, which she paired with trendy $745 PVC and gold heels from Gianvito Rossi, before slinging a vintage Chanel jacket around her shoulders in a style favored by fashion editors the world over.

Amal finished off the ensemble with a pair of doorknocker-style earrings, glamorous makeup, and loose waves in her long brunette locks, which she had tucked over one shoulder as she made her way out of the venue, before heading to The Carlyle, another luxury five-star hotel located less than a block away from The Mark.

No show: Interestingly, Meghan's mother Doria Ragland, 62, was not in attendance at the shower, and was photographed at home in Los Angeles at the same time that the event was taking place in New York

And she was not the only one who pulled out all the stops style-wise; the lucky guests invited to attend the event turned the city sidewalk into a fascinating spectator sport, when they began both arriving at and departing from the swanky venue where the event was being held - battling through snow and sleet in the process.

Human rights lawyer Amal, who is married to actor George Clooney, was joined at the venue by a host of Meghan's nearest and dearest, including designer TV anchor Gayle King, designer Misha Nonoo, stylist Jessica Mulroney, Suits star Abigail Spencer, and makeup artist Daniel Martin. Co-host Serena, 37, was already at The Mark, having chosen to stay at the hotel with Meghan the night before.

Interestingly, Meghan's mother Doria Ragland, 62, who is arguably her closest and most beloved family member, was not present, and was actually pictured at home in Los Angeles at the same time the shower was taking place in New York City.

None of the royal family was in attendance at the event either; Prince Harry's cousin Princess Beatrice, who actually lives in New York City, where she works at software firm Afiniti as the vice president of partnerships, was not pictured at the hotel on Wednesday, nor is she thought to have made an undercover appearance at the event.

Meghan's sister-in-law Kate Middleton also failed to attend the event, however it is thought that she may be present at a second, more low-key baby shower being thrown for the expectant mother in the UK next week, after she and Prince Harry return from their trip to Morocco this weekend.

There were however plenty of other guests on hand to ensure that Meghan had a wonderful afternoon, with many of them strutting their stuff for the cameras on their way into The Mark, which has turned into something of a tourist hotspot in the days since Meghan's arrival in Manhattan.

But it was Amal who truly stole the sidewalk fashion show, turning heads in her bright red Sergio Hudson jumpsui and trendy PVC-and-gold shoes.

Bling thing: As she left, newly-engaged designer Misha Nonoo showed off a glimpse of the engagement ring that she received from oil heir Michael 'Mikey' Hess when he popped the question during a Valentine's getaway in Mexico

The end of the fun: Actress Abigail Spencer,

Long-time pal: Soho House consultant Markus Anderson, who was not seen arriving at the event, made his way out of the hotel just in front of several $225 Away carry-on suitcases that were gifted were guests at the shower

Beauty guru: Makeup artist Daniel Martin, who did Meghan's bridal beauty look for the royal wedding, was seen making a call on his iPhone as he headed out into the rain

Leftovers? One of Meghan's oldest friends, fellow Northwestern alumnus Lindsay Roth (right), walked out of the hotel with a woman who is believed to be the duchess's sorority sister Genevieve Hillis and who was carrying small plastic container

Presents for everyone! One guest, who was seen arriving with a large cake box in her arms, left empty-handed, however she was followed by a man carrying several Away suitcases, which are believed to be being sent out to the guests

Meghan and Amal are thought to have been friends for several years now, having been brought together by their respective husbands, actor George and Prince Harry, who have been close pals for many years.

The foursome are said to have spent a lot of time together, thanks in large part to the fact that they are all based in the UK, with George, 57, and Amal residing in a stunning property in Oxfordshire, which Meghan and Harry are believed to have visited on a number of occasions.

Earlier this month, George actually spoke out to defend Meghan, insisting she has been 'pursued and vilified' in the same way that Prince Harry's late mother Diana was.

There were also reports that the Hollywood star would be asked by Prince Harry and Meghan to serve as the godfather to their firstborn child, although he was quick to shut down those rumors, explaining that has his hands full with his own twins.

But Amal clearly still wanted to play a key role in the celebration of Meghan's unborn child, and by all accounts was one of the driving forces behind the shower, along with tennis pro Serena.

Amal was one of the earlier arrivals at the baby shower venue, turning up at around the same time as Meghan's close friend and unofficial stylist Jessica Mulroney, who was also stylishly dressed in a long black $750 Mackage overcoat, black pants and a $58 orange turtleneck from Aritzia.

Despite the snow, the mother-of-three followed in Amal's footsteps and wore a pair of chic high heels, opting for a dusty pink-orange shoe that complemented her figure-hugging shirt.

Many of the guests seemed to ignore the heavy snowfall, perhaps opting for style over comfort and practicality in light of the special occasion and the hoards of photographers stationed outside waiting to snap their picture.

CBS co-anchor Gayle, 64, arrived at the shower in a very bright outfit, wearing a bright purple coat and a pink and purple furry scarf over a bright pink dress. She added a pair of matching pointed-toe heels to the look, and also added a brightly-colored rainbow snakeskin-print clutch bag, which actually perfectly matched the large rainbow gift bag she also had in her hand.

Getting the party started! Amal made a bold arrival at the event earlier in the day, bringing a bit of bold color to a snowy and gray New York City day

Snow problem! Despite the cold weather and falling snow, the mother-of-two chose to go without a particular thick coat, instead just draping a black Chanel jacket around her shoulders

Getting ready: Amal was one of the earlier guests to arrive at the event, while tennis pro and co-host Serena did not make a public entrance, having stayed at The Mark with Meghan overnight

Keeping it cool: The human rights lawyer appeared unfazed by the photographers as she arrived at the hotel, and was greeted by one of the many staff on-hand to help guests

Gift giving! Gayle brought a large rainbow gift bag with her when she arrived at the event, no doubt filled with a gift for the expectant mother and her unborn child

Winter wonderland: Like many of the guests, Gayle was caught in the snow as she exited her vehicle and headed inside

Moving on up: Gayle, who actually covered Meghan's wedding to Prince Harry for CBS, has not previously spoken about her friendship with the duchess

Strutting her stuff: Meghan's unofficial stylist Jessica arrived at the venue at around the same time as Amal, and had some help from a staff member with an umbrella as she walked in

Snow queen: Jessica, 39, wore a $750 Mackage coat, and was carrying her own umbrella, along with a large black leather clutch, but she chose not to use it for the short walk into the hotel, instead braving the snow

Ready to celebrate! Meghan, pictured heading to dinner in New York City on Tuesday night, was thrown the no-expenses-spared bash by Serena and Amal, before she returns to London

Gayle was perhaps most the surprising guest at the shower; her friendship with Meghan is not something she has commented on previously, although her best friend Oprah is known to have formed a close bond with the duchess and her mother, and actually attended the royal wedding back in May.

The cost of Meghan's New York baby shower The Mark Hotel Grand Penthouse Suite - $150,000 Five nights in a one-bedroom suite at The Mark Hotel - $9,982.05 Dinner for five at The Polo Bar - approx. $420 with drinks Lunch at The Surrey - Cafe Bolud - approx. $78 Afternoon tea for two at Laduree - approx. $25 Two Royal Protection officers - $86,316 British Airways flight from London to NYC - $26,202 Harp player Erin Hill - $625 17 Away carry-on suitcases - $3,825 Gifts: Babyletto Hudson 3-in-1 Convertible Crib - $379 10ft mandarin tree - approx. $140 Lady Fleur NYC roses - approx. $399.95 Trek bicycle - approx. $609.99 Carnival King cotton candy machine - $199.99 TOTAL: $279,201.98 Advertisement

Her friend Gayle meanwhile was tasked with covering the event for CBS, a job she took on with great enthusiasm and energy, even revealing at the time that she was something of a royal fan, particularly when it came to Prince Harry's late mother Princess Diana.

'I’ve loved the royals for a long time,' she said of her trip to London to cover the wedding. 'I was the girl who got up to watch Princess Diana get married, because I thought she was so cool. There was just something about her that was so different, so I followed everything about her... from the courtship to the marriage and then, unfortunately, to the funeral.

'To see the video of William and Harry walking behind the casket, I remember thinking, "I hope her boys are going to be OK," Now, to see them all grown up, it’s all very exciting to me.'

She did actually get the chance to meet and spend time with Prince Harry in the summer of 2017 however, revealing that she and the royal ended up at the same retreat together, and ended up having dinner along with British TV host James Corden.

'I’m not saying that Harry and I are great pals, but it was fun to spend even a little bit of time with him,' Gayle said of the exciting encounter.

Meghan's former Suits co-star Abigail Spencer was the first guest to arrive at the hotel, and she was followed closely by the duchess's makeup artist Daniel Martin, the man behind the royal's stunning bridal beauty look for her wedding to Prince Harry last May.

Daniel, who is a brand ambassador for Dior Beauty, was quite literally wearing his heart on his chest when he arrived at the hotel in an all-black ensemble that included a hoodie with the message, 'Thank you for being a friend' written across it in white lettering.

A double celebration: Newly-engaged designer Misha Nonoo - who is credited with introducing Meghan and Prince Harry - was seen carrying a large white bag from high-end interiors company Rani Arabella into the hotel

For the newborn? Rani Arabella, the company from which Misha appears to have purchased her gift, sells all manner of high-end homeware pieces, including baby blankets that retail for between $315 and $375 each

The party starter: Meghan's former Suits co-star Abigail Spencer was one of the first guests to arrive at the venue, with the actress making a very low-key entrance, seemingly arriving in the back of a yellow taxi with plenty of baggage

Get a grip! The 37-year-old was seen wheeling a silver Away suitcase, while also carrying a large brown gift bag, a brown backpack, and a black and gold handbag over her shoulder

Getting in there: Co-host Serena, 37, was staying at The Mark with Meghan on Tuesday night, however she took to Instagram on Wednesday morning while everyone else was arriving to promote the own-brand outfit she was wearing

Promo op! The tennis pro did not walk in front of photographers in the morning like the rest of the guests, but she still made sure to share details of her outfit, saying she feels 'grateful' for the pants which say, 'I am beautiful, I am strong'

The hoodie, which is from trendy brand Ami, is by no means you're average sports store sweatshirt however, with the stylish item costing an impressive $290. That price pales in comparison to the makeup artist's Off-White x Nike sneakers, however, which retailed for a staggering $749 per pair.

37-year-old Abigail meanwhile, was wearing a long flowing skirt and a black sweater, but concealed her face somewhat in a dark baseball cap and large sunglasses.

She was also laden with bags when she turned up at the hotel, arriving just a few minutes before Daniel with a silver Away carry-on, a large brown paper bag - likely filled with a gift for Meghan - and two other, smaller purses, one over each shoulder.

Interestingly, her metallic suitcase was by the same brand that donated $225 carry-on bags to each of the guests at the shower; two women were seen stacking up the luggage outside of the hotel earlier on in the day before wheeling it into the venue for the event.

The Suits star was quickly relieved of the items however, with a helpful staff member rushing to her aid in order to bring the larger bags into the hotel for her, allowing her to better showcase her boho-inspired look.

It had been previously reported that Meghan's shower, which is said to be the main reason for the seven-months-pregnant royal's secret trip to the Big Apple, had taken place on Tuesday, however a source later revealed that it was actually scheduled for Wednesday, shortly before Meghan is set to return to London.

Speaking to Tatler, the insider revealed that the baby shower would be held in the Grand Penthouse Suite at The Mark hotel on New York's Upper East Side, where Meghan and her friend Serena, 37, stayed on Tuesday evening, after enjoying dinner together at a swanky Manhattan restaurant.

Although it is not known whether Meghan has been staying in the penthouse for her entire trip - which began on Friday when she flew in from London after spending Valentine's Day with her husband Prince Harry - the location was picked as the perfect place to host the duchess and several of her closest pals while they celebrated the upcoming arrival of Meghan and Harry's first child.

Described by the hotel as 'A Castle in the Sky', the 10,000sq ft suite boasts every luxury, including a 2,500sq ft rooftop terrace overlooking Central Park, five bedrooms, four fireplaces, six bathrooms, two powder rooms, two wet bars, a dining room, a conservatory, and a living room that can be 'transformed into a full-size Grand Ballroom' if desired by guests.

The two-story penthouse, which is located on the 16th floor of the hotel, is described on The Mark's website as being 'lavishly-adorned' and 'unprecedentedly spacious', and features 'majestic' interior decor designed by legendary French interior designer Jacques Grange.

According to Tatler's source, the location was chosen by Serena, who is a long-time fan of The Mark's in-house restaurant, The Mark by Jean-Georges, a renowned chef whose flagship restaurant on Central Park West boasts two Michelin stars, however she is not thought to have stayed at the hotel before Tuesday night, after she and Meghan enjoyed dinner with two of the royal's closest friends Jessica Mulroney and Markus Anderson.

Mother-of-one Serena is also said to be footing the bill for the use of the pricey hotel room, who has been a close friend of Meghan's since they first met in 2010. She is said to have chosen the location after 'visiting several other properties in the area', according to the source.

Glam squad! The seven-months-pregnant duchess's makeup artist Daniel Martin - the man behind her bridal beauty look for her wedding to Prince Harry - was also among the first to arrive, no doubt because he was helping her to get ready

Special message: Dior Beauty ambassador Daniel made a very public - and very sweet - declaration as he walked into the hotel, wearing a hoodie that featured the message, 'Thank you for being a friend'

Fitness favorite! Trainer Taryn Toomey, creator of a workout called The Class that is loved by the likes of Naomi Watts and Jennifer Aniston, arrived at the event carrying two large white bags and a large sports bag

Party people: Many of the guests came baring gifts, with one woman carrying what appeared to be a cake (right), while fashion publicist Celine Khavarani (left) brought a white bag with her

Firm friend: One of Meghan's oldest pals, Lindsay Roth, who she at Northwestern University, was one of the final guests to arrive, carrying with her a colorful gift bag with two elephants on the side

Feeling blue: One guest (left) made the brave decision to go bare-legged, despite the chilly New York weather, while another, a man seen carrying two gift bags (right), looked much cozier in his winterwear

The inside source also revealed that the shower was set to include a host of elegant activities, kicking off with a flower arranging lesson that will be accompanied by a variety of delicious desserts prepared especially by the hotel restaurant's head chef, Jean-Georges Vongerichten.

Jean-Georges himself was believed to have be present at the start of the event in order to personally greet Meghan and her guests upon their arrival in the suite.

Other guests pictured arriving at The Mark ahead of the baby shower included newly-engaged designer Misha Nonoo, who looked chic in a gray plaid coat, Lindsay Roth, Meghan's closest pal from Northwester University, and fashion publicist Celine Khavarani.

Misha, who seems to have spent a lot of time with Meghan since the royal arrived in the US on Friday, looked every inch the fashion favorite as she made her way into the event, wearing a short black skirt and a simple gray sweater under her long button-up jacket.

She finished the look off with a pair of heeled boots and a black and white purse with a gold chain handle; Misha, who got engaged to oil heir Michael 'Mikey' Hess during a Valentine's Day getaway in Mexico, was also seen carrying a white shopping bag from high-end interiors store Rani Arabella.

The company sells all manner of luxury home decor pieces,

It was also reported that hairstylist Serge Normant - the man who styled Meghan's locks for the royal wedding - was due to be in attendance - as was Soho House consultant Markus Anderson, who is believed to have had a hand in arranging Meghan and Harry's first blind date, and was pictured heading to dinner with the royal at The Polo Bar on Tuesday night.

NBCUniversal Cable Entertainment Group chairman Bonnie Hammer was also included in the names of potential guests, however none of them were photographed outside the venue on Wednesday.

Something fun! It appears as though one of the guests brought a bike for Meghan's unborn child, with a staff member from the hotel seen carrying the large Trek box into the venue. The brand's kids' bikes start at $169.99 and go up to $1,049.99

Something special? A large garment bag was one of many deliveries seen being made to the hotel ahead of the baby shower

Stack 'em up! Not long before the shower was due to start, around 17 $225 carry-on suitcases from trendy travel brand Away were delivered to the hotel

Gifts: The suitcases are said to have been given to the duchess and her guests as a gift by the brand. They were seen being delivered to the hotel by two women just over an hour before the shower's reported start time

The entertainment! Harpist Erin Hill was seen wheeling her large instrument into the venue, suggesting that she may providing music for the guests at the shower to enjoy

Dress-down: The musician was wearing a rather casual pair of purple trousers, and a pair of blue sneakers, however it is likely that she planned to change once inside the venue

Sweet treats! A team of caterers was also seen delivering several boxes, including a cotton candy machine, which may well be intended for Meghan's shower

Supplies? Several of the boxes were labeled with 'Jean-Georges', the head chef at The Mark, who is reportedly providing catering for the baby shower, and it set to greet Meghan and her guests personally

Heavy lifting: Some of the boxes were carried in by members of the catering staff

It was initially reported that the bash was being co-hosted by Serena and Amal, 41, who attended Meghan and Harry's wedding along with her husband George, however attendee Gayle King later revealed that the elegant event was in fact organized by tennis pro Serena, stylist Jessica, and Meghan's sorority sister Genevieve Hillis, on e of the royal's closest friends from Northwestern University.

Meghan's close pal and fellow screen star Priyanka Chopra, who was a guest at the former Suits star's wedding to Prince Harry, all but confirmed that she would not be attending the baby shower, when she posted a selfie on her Instagram account on Tuesday afternoon, and listed Beverly Hills, California, as the geographical location of the snap.

It was thought that Priyanka - who, like Meghan spent Valentine's Day in the UK - might have joined the royal on her trip over to the Big Apple in time for the shower, but it now appears that is not the case.

Meanwhile, pilates instructor Heather Dorak, another close friend who attended the royal wedding, welcomed her second child, a baby boy named Cody Cohen, on Valentine's Day, which presumably left her unable to attend the event.

But before any of Meghan's lucky guests were seen arriving, The Mark was abuzz with furious activity as staff prepared for the very high-profile event, with numerous deliveries seen being made throughout the morning, from catering boxes to a stack of Away carry-on suitcases to harpist Erin Hill, who brought her instrument and music stand with her.

The catering delivery included several boxes marked with the name 'Jean-Georges', suggesting they are supplies for the food he will be preparing for the mother-to-be and her guests, as well as a cotton candy machine, which may well be used to whip up some sweet treats for the party.

And that's not the only treat in-store for Meghan and her guests; shortly after the catering delivery, around 17 carry-on suitcases from trendy travel brand Away were seen being wheeled into the hotel on a luggage cart, each encased in its own white branded dust bag.

The suitcases, which have been carried by a host of celebrities, including the likes of Elizabeth Olsen and Hailey Bieber, cost $225 each, and were - a source told DailyMail.com - gifted to the pregnant royal by the brand. It is highly likely that the suitcases, which each come with their own removable battery, will be given to each guest at the shower, potentially in order to carry other gifts that they may receive.

Lavish: The baby shower is taking place in the Penthouse Suite at The Mark, which is widely reported to be the most expensive per-night hotel room in the US

Plenty of room! The large suite, which has a stately dining room, is more than capable of accommodating Meghan and 15 of her closest friends, with many reports suggesting that is how many were invited to attend the intimate celebration

Queen of the castle: The 10,000sq ft penthouse, which is described by The Mark as 'A Castle in the Sky' boasts a 2,500sq ft roof terrace that overlooks Central Park

Views: There is also a conservatory in the penthouse, meaning that Meghan and her guests will be able to enjoy the impressive views from the comfort of the suite, instead of facing the chilly weather

Relaxation: The penthouse features multiple common areas where Meghan and her guests can sit and relax, including a Library Lounge that has plenty of books stacked up for patrons to enjoy

Cozy: There are four fireplaces scattered throughout the enormous suite, including several of the general living areas (left), and there are also five bedrooms, although it is not thought that Meghan is using the suite to stay in

Shortly after the suitcases were wheeled into the hotel, renowned harpist Erin Hill arrived at the location, wheeling her large instrument into the venue, while a helper followed on with her music stand - sparking speculation that she will be providing at least some of the entertainment at the lavish bash.

On Tuesday evening, Meghan was pictured heading out to Ralph Lauren's swanky restaurant The Polo Bar on Tuesday night alongside fellow mothers Serena and Jessica, perhaps finalizing plans for the lavish baby shower set to take place today.

Despite a busy day spent catching up with friends, Meghan looked fresh-faced and full of energy as she arrived at the high-end eatery - which is also known to be a favorite of President Donald Trump's, and is located just a few block's from his tower on Fifth Avenue.

The party spent three hours inside the restaurant before stepping back out into the chilly New York night. Meghan and Serena were then spotted arriving back at their lavish hotel, The Mark, on Manhattan's Upper East Side.

Jessica, a Canadian stylist who has been helping best friend Meghan with her outfit choices for years and has three children: twins Brian and John, aged eight, and daughter Isabel, aged five. Serena has a one daughter, Alexis Olympia Ohanian Jr, aged one.

Mother-to-be Meghan looked every inch the glamorous royal as she made her way into the restaurant, escorted by the same group of burly officers from the State Department and royal protection officers.

The pregnant duchess recycled the same $3,085 (£2,250) navy Victoria Beckham coat that she was seen wearing in images published exclusively by DailyMail.com on Monday evening - the first photos taken of Meghan since she arrived in the Big Apple on Friday evening.

She paired the chic double-breasted coat with a black scarf, a pair of black satin boots - thought to be from Isabel Marant - and a $1,140 (£915) black chain-handle handbag by vegan designer Stella McCartney.

Meghan also modeled a much more glamorous makeup look than she had been seen wearing during the day, modeling a dark smokey eyeshadow, while emphasizing her natural pregnancy glow with some highlighter and bronzer.

As the former actress climbed out of her SUV - which appeared to be the same State Department vehicle she has been using all day - she couldn't help but flash a wide smile, no doubt at the prospect of spending an evening with some of her closest pals, many of whom live an ocean away from the royal's home with Prince Harry at Kensington Palace.

Meghan's husband may well have been in her mind however thanks to the choice of venue.

Not only is The Polo Bar known to be a much-loved celebrity haunt, the restaurant is also themed entirely around the popular equestrian sport from which it takes its name, a sport that Prince Harry has been playing for decades.

On the town! On Tuesday evening, the 37-year-old royal was pictured heading to dinner at Ralph Lauren's restaurant The Polo Bar alongside Serena, Jessica Mulroney, and Soho House consultant Markus Anderson

Beaming: Meghan positively glowed as she made her way into the restaurant, which is known to be one of President Donald Trump's favorite eateries, and is located just a few blocks from his tower on Fifth Avenue

Gal pals! The pregnant royal was joined by mother-of-one Serena, 37, who looked trendy in her low-key outfit of black jeans, a black sweater, and a long black jacket with fun pink plaid detailing on the sleeves and sides

The pair were all smiles as they walked out of the midtown Manhattan restaurant on a chilly night

Strutting her stuff! Meghan's unofficial stylist and GMA fashion correspondent Jessica Mulroney was also in attendance at the dinner, flaunting her fashionable taste in a chic ensemble that featured a $890 plaid Mackage coat with a leather belt

Here we go: Markus, who is thought to have had a hand in setting up Meghan and Prince Harry, linked arms with his royal pal to walk alongside her as they headed into the restaurant together

She looked up from her hand towards a waiting crowd of fans and photographers as she finished the short trip back to her hotel, a few blocks away from The Polo Bar

Meghan and Serena have actually watched one of Harry's polo matches together, along with the tennis pro's husband Alexis Ohanian, who joined the two women to cheer on the prince in the Audi Polo Challenge in Oxfordshire back in July, not long after Meghan and Harry tied the knot.

And there would have been plenty of reminders of that fun summer day inside the restaurant.

In the main dining room, which is located downstairs, diners are met with a myriad of equestrian-themed artworks that cover the walls, while riding helmets and polo mallets can be found hanging on hooks near the bathroom, just waiting for a few social media-savvy patrons to pose for a photo or two.

Upstairs, the is an intimate bar area, where diners can enjoy one of the many cocktails on the extensive menu, which not only features classic cocktails like the Moscow Mule and the Old Fashioned, it also boasts a number of signature reserve cocktails, including the Jockey Club and the Improved Negroni.

There is even a drink on the menu named after Meghan's father-in-law, the Prince of Wales, a $22 drink that is made of High West Rendezvous Rye, Cherry Heering, honey, pineapple, and Champagne.

The restaurant also boasts an extensive wine list, featuring bottles from around the world, including a particularly pricey $18,000 1891 Brunello di Montalcino.

As for the food, which was no doubt pregnant Meghan's focus, as opposed to the alcohol offerings, The Polo Bar boasts a host of classic American dishes, from a house chopped salad that retails for $18 to a 16oz New York strip steak, which costs $55.

The restaurant even has its own signature hot dog, the $20 RRL Hot Dog, which comes complete with sauerkraut, sweet relish and mustard, all served on a toasted brioche bun.

Having opened in early 2015, The Polo Bar quickly became one of New York's most popular eateries for high-profile diners, and has played host to everyone from Hillary Clinton to Gwyneth Paltrow.

President Trump, Melania, and their son Barron also enjoyed dinner at the eatery back in June 2016, the night before Donald's 70th birthday, and just a few months before he went on to win the presidential election against Clinton.

Meghan's evening outing came after a busy day of activities for the royal, which started early in the afternoon when she was seen leaving high-end New York hotel The Mark to enjoy an afternoon out.

The seven-months pregnant royal was seen cradling her baby bump as she made her way to Met Breuer museum, which is located just a few blocks away from The Mark hotel - with her former Suits co-star Abigail Spencer joining her for the quick city jaunt.

Moments earlier, Meghan was pictured walking out of the five-star hotel at 1:05 pm, once again keeping a hand rested on her growing bump, surrounded by armed officers thought to be from the State Department, as well as several plain clothes royal protection officers, just moments after her close friend and former Suits co-star Abigail Spencer was pictured making her way into the venue.

Taking advantage of what is a bright and sunny day in the Big Apple, Meghan wore a vintage gray Courrèges coat for her surprise outing, pairing the outerwear with some skinny black jeans, and some nude suede heels.

She accessorized her ensemble with a pair of dark sunglasses, which hid much of her face from the cameras, and was seen carrying a dove-gray handbag in the crook of her right arm, while the other hand was planted firmly on her large bump.

Meghan was accompanied on the trip by what appeared to be several members of hotel security, as well as a handful of plain clothes police officers, including the same man seen escorting the mother-to-be out of a Manhattan apartment on Monday evening.

Other than her impressive security detail, the royal appeared to be along as she made her way past photographers and into a waiting SUV, which had Department of State license plates.

From there, she traveled the two-block distance to the Met Breuer museum, arriving at 1:10 pm, and was pictured spending time in the restaurant after her arrival, however a source revealed that she also found time during her 30-minute visit to take in some of the museum's artworks during a tour around one of the galleries, noting that the Duchess 'looked beautiful' during her visit.

However a source at the museum told DailyMail.com that Meghan was initially supposed to have lunch at the Met Breuer, but made a last-minute change of plans because the venue was felt to be 'too public' thanks to the large windows in the restaurant, which make it easily viewable from the street outside.

Because of this, Meghan, Abigail, and their entourage of protection officers, chose a more secure, private location for the royal to enjoy more of an incognito lunch - The Surrey hotel.

Meghan's very brief trip to the Met Breuer was enough to provide a bit of excitement and intrigue for some however, with a few social media users sharing their shock at running into her in the art gallery - with one person revealing that they bumped into the duchess in the bathroom.

'I went to see Julio le Parc at the Met Breuer and also ran into Meghan Markle in the bathroom,' Instagram user Ashley Toth wrote, while sharing an image of one of le Parc's pieces. Ashley then saw the duchess again while 'walking home', sharing an image of Meghan and Abigail exiting The Surrey hotel.

Actress Abigail, also 37, also joined the royal at the museum, before the pair left together to walk the short distance across the street to The Surrey hotel - another high-end establishment that has played host to a slew of high-profile clients, from JFK to Bette Davis.

Chic: The Polo Bar boasts a sprawling downstairs dining room that affords patrons plenty of privacy from the outside world, while allowing them the opportunity to enjoy numerous equestrian-themed works of art

Memories! No doubt the theme of the restaurant brought back fond memories for Meghan, whose husband Prince Harry, seen in June, has been a keen polo player since he was a young boy, as are his father Prince Charles, and brother Prince William

Close bond: Meghan has seen her fair share of polo matches since starting her romance with Prince Harry, and always appears happy to lend her support at the side of the field, as she did back in July

Meghan and Abigail were flanked by two of the same royal protection officers seen escorting Meghan out of The Mark, with Meghan walking just a few paces ahead of her friend, flashing her three-diamond engagement ring as she placed her hand on her baby bump while crossing the road.

Suits star Abigail was wearing the same red patterned shirt dress that she was seen modeling when she arrived at the hotel earlier on, but she had abandoned the gray beanie that she sported with it; she also traded the thick fur-trim parka she had been sporting, in favor of a more lightweight black jacket, allowing her to show off more of her colorful dress.

The duo spent just over an hour at The Surrey, perhaps taking the time to enjoy a light lunch.

At approximately 3pm, the friends were seen leaving the hotel in order to make the very short journey back to The Mark, arriving around three minutes later - presumably just in time to start getting ready for the main event of the day, Meghan's baby shower.

Shortly after their return, newly-engaged designer Misha Nonoo - the woman credited with introducing Prince Harry and Meghan - was seen arriving at The Mark, having spent much of the day at her studio in NoHo, before going to join her royal pal.

It is a double celebration for Misha, 34, who got engaged to oil heir Michael 'Mikey' Hess, 32, during a Valentine's vacation in Mexico, with the groom-to-be proudly sharing the happy news on social media, before the designer was seen wearing her dazzling new diamond ring while out and about in New York on Tuesday.

That same ring was front and center as Misha made her way into The Mark, wearing the same chic, but low-key, outfit that she was pictured modeling earlier in the day, when she left her Manhattan apartment in the morning, and when she stepped out to grab a salad for lunch.

The bride-to-be bundled up against the chilly New York weather in a dark blue overcoat, black tights, and a bright red scarf, finishing the look off with a pair of heeled black ankle boots.

Misha was also seen carrying her iPhone, and a small personalized red purse that had her initials MN embossed on the bottom corner.

Time for some culture: Earlier in the day, Meghan spent time enjoying the sights and sounds of the Upper East Side, including a trip to the Met Breuer art museum

Swapping it up: The royal reportedly wanted to have lunch at the Met Breuer, however the museum's restaurant was deemed 'too public' because of its vast windows that could be seen from the street, a source told DailyMail.com

Outing: After visiting the Met Breuer, Meghan and her former Suits co-star (pictured to the right) walked across the street from the museum to another hotel - this time The Surrey, another high-end venue located just a stone's throw from The Mark

Gal pals: Meghan and Abigail are thought to have enjoyed a spot of lunch at The Surrey, before leaving the high-end hotel and making their way back to The Mark

Ready to party! Meghan arrived back at The Mark shortly after 3pm

Here come the guests! Just after the duo's return, newly-engaged designer Misha Nonoo - the woman credited with introducing Prince Harry and Meghan - was seen making her way into The Mark

Although Meghan managed to spend a few hours away from the hotel, the venue was still alight with feverish activity even in her absence, with crowds gathering outside its main entrance in the hopes of catching a glimpse of the duchess, one of her close friends and guests - or at the very least one of the many fascinating deliveries arriving ahead of her shower on Wednesday.

Abigail was the first of the royal's nearest and dearest to be seen making their way into The Mark hotel on New York's Upper East Side - trying to maintain a low profile by wearing a gray beanie hat and large, dark sunglasses as she made her way inside, flashing a wave at the waiting photographers on her way in.

She spent just a few minutes in the hotel, taking the time to change up her outfit slightly, before heading out again to join Meghan at the Met Breuer.

Abigail first sparked speculation that she had traveled to the Big Apple for the special occasion after sharing an airport selfie on her Instagram account on Monday - less than 24 hours before she was seen making her way into The Mark, shortly after bouquets of flowers, an orange tree, and a $380 travel crib were seen being delivered to the swanky venue.

As well as her shades and hat, the actress was dressed in a thick black parka with a fur-lined hood upon her arrival, showing off just a hint of the more colorful, stylish pink dress seen poking out from underneath the thick winterwear.

Meghan managed to make a very under-the-radar arrival in the city however, going almost entirely unseen by the public over the weekend, after reportedly arriving on Friday evening.

On Monday night, the duchess attempted to go incognito as she covered up in a cap and long navy Victoria Beckham overcoat and a gray newsboy cap pulled down over her dark brown hair - and with her large diamond engagement ring clearly visible on her wedding finger.

Meghan returned to the Big Apple over the weekend to spend time with her girlfriends before the arrival of her first child this spring, and was seen on Monday evening being escorted into an SUV by a royal protection officer.

The palace declined to comment on Meghan's security detail for the duration of the trip, or the plain clothes officer seen accompanying her.

Meghan is understood to have flown into the city on Friday for a surprise five-day trip after spending a quiet Valentine's Day evening with her husband, Prince Harry. A spokesperson for Kensington Palace would not divulge details of the Duchess's flights, but confirmed that as this is a personal trip, her travel was 'privately funded'.

It is not known whether Meghan flew to New York on a commercial flight, or whether she was lucky enough to travel in a private jet.

The royal certainly has her fair share of high-profile pals who may have been able to secure her access to a private plane; TV mogul Oprah, who was in attendance at the royal wedding, and is said to have formed a close bond with Meghan's mother Doria, owns a private jet, and once said of the plane that it was incredibly useful for making the exact trip that the Duchess of Sussex made on Friday.

'I would say having your own airplane is the greatest luxury,' Oprah told British Vogue editor Edward Enninful during a 2018 interview, before adding: 'Because it means one minute you're in New York, and then the next minute you say, "You know Edward, I think I'll fly to London."'

Caught up! Several people were seen making their way into the hotel either shortly before or after Meghan's return, however it is thought that a number of them were guests arriving for a stay, rather than attendees of the royals' baby shower

Lightweight! There were a few people seen arriving without suitcases in tow, suggesting that they were there for something less long-term than a hotel stay, and were perhaps lucky enough to be attending the shower

Gifts for the baby? One woman was pictured arriving at The Mark with two large bags from Crate & Barrel, which may well have been filled with presents for expectant mother Meghan

Her fellow royal wedding guests David and Victoria Beckham regularly travel via private jet with their family, as does George Clooney, another attendee at Meghan and Harry's stunning ceremony back in May.

A private jet would certainly have made for a more comfortable flying experience for the pregnant duchess, who is expecting her first child in the spring, and is believed to be just a matter of weeks away from her due date.

Despite being so far along in her pregnancy, Meghan is still perfectly safe to fly, according to advice offered by the Mayo Clinic, which suggests that expectant mothers can continue to travel via air until they are 36-weeks along; Meghan is currently thought to be in week 29 or 30 of her pregnancy.

And Prince Harry certainly doesn't seem to have any qualms about flying privately; the father-to-be actually chartered himself a jet to the tune of $26,100 (£20,000) in order to return home from Norway on February 14 so that he could spend his first Valentine's Day as a married man with his pregnant wife.

The duke made his round trip in a double-engine Cessna Citation Excel for the three-hour visit to the Bardufoss air station, 200 miles (322km) within the Arctic Circle. The state-of-the-art 18ft plane flies in and out of smaller airports while offering 'the comfort and amenities of a midsize cabin jet' according to Cessna.

A direct chartered flight on the Citation Excel - based on a seven-hour round trip from Farnborough to Bardufoss, where Harry was traveling to and from, for seven people - would cost between $23,000 (£18,200) and $28,000 (£21,450) according to Luxaviation.

Last October, the Duke and Duchess of Sussex were caught up in a mid-air scare when their private jet was hit by lightning.

The couple was travelling to an opening party in Amsterdam when their luxury Dassault Falcon 7X was reportedly struck.

A bolt of lightning struck the nose cone, narrowly avoiding the navigation equipment. Around 30million volts surged through the plane's fuselage.

After the dramatic scare, the plane - which would have set the Duke and Duchess back around $26,100 (£20,000) for a return flight to Amsterdam - managed to land safely at Schiphol Airport.

Honored guests: Meghan's close friend and former co-star Abigail Spencer was arriving at The Mark hotel shortly before the royal was pictured leaving the venue

Special delivery! Her arrival comes shortly after a huge bucket of pink roses was seen being delivered to The Mark on Tuesday afternoon, ahead of Meghan's lavish baby shower

For luck: An orange tree was also seen being delivered to the hotel ahead of the baby shower; in Eastern tradition, mandarin oranges are believed to represent prosperity, happiness and luck, particularly in the New Year

Step aside! As well as the flowers, staff at the hotel were also seen wheeling in a large box housing a $379 travel crib, which may well have been a gift for the duchess, or a prop for the party

According to Private Fly, it could cost anywhere between $78,376 (£60,000) and $379,000 (£290,000) to charter a return flight on a private jet from London to New York, depending on the size and make of the plane, and the number of days it was required to be on call.

And while it has not been confirmed whether or not Meghan flew on a private plane, the trip certainly seems to have been focused around ensuring that the mother-to-be was as relaxed and happy as possible. Her low-key itinerary is said to have already included shopping and plenty of good food, but the main event of the trip is a baby shower with 15 of her closest friends at a hotel on New York's Upper East Side.

On her way! Abigail first sparked speculation that she was headed to Meghan's baby shower when she shared this image of herself with a suitcase on Instagram on Monday

The intimate event, due to take place today, is believed to have been organized by her best friend Jessica Mulroney - who arrived in the city at the end of last week from her home in Toronto.

'The trip is a lovely chance to catch up with friends and spend time in a city she loves.'

This will be the last time a lot of them will see Meg until after the baby is born so it’s nice to share precious moments,' a source told Harper's Bazaar.

Meghan kept her head down as she made her way to the SUV on Monday night, with her dark hair covering the side of her face. She carried a second wide-brimmed black hat - believed to be a £160 ($195) design from Rag & Bone - in her hand, along with a white bag.

But while the Duchess of Sussex appeared to be making an attempt to go under the radar in her low-key ensemble, the large diamond engagement ring on her wedding finger was unmistakable.

Her husband had the three-stone design made for her especially ahead of their engagement in 2017, using one diamond that he sourced in Botswana, where the couple holidayed together early on in their relationship.

The dazzling design was clearly visible as Meghan made her way down the steps and into the car, carrying her spare hat and a simple white bag that may well have contained a gift.

Her nails appeared to be painted with a subtle sheer pink shade - a much more low-key polish option than some of the darker, bolder colours she has been known to model, despite royal traditions suggesting that only the most subtle of nude shades should be worn.

In her other arm, the expectant mother had a large gray leather handbag held in the crook of her elbow.

Incognito: Meghan Markle was seen stepping out in New York City on Monday evening after flying into the city to attend a baby shower organized by her closest friends

Helping hand: A bodyguard escorted the royal down a small flight of stairs during the outing, and was seen guiding the mother-to-be towards a waiting SUV

Catching up: This trip is thought to be the last one that Meghan (pictured left and right with her husband in London last week) will make to the US before the birth of her child in a few months

The bodyguard who escorted her to her waiting vehicle also appeared to be carrying a few of her possessions, including a Lululemon tote bag that was covered with Meghan's tan wool coat, suggesting the royal may have had more than one outfit option on-hand.

Meghan appeared to be going out of her way to remain unrecognizable during the short walk to the SUV, keeping her head lowered, and her hair pulled across her face - a far cry from the smiling, hands-on appearances for which she has become known at pubic events.

Her bodyguard also attempted to blend in, wearing a pair of charcoal-gray trousers, and a quilted blue coat with a hood. He also carried a phone in his hand, along with Meghan's belongings.

Kensington Palace did not comment on the details surrounding the royal's security detail during the trip, and it is not known whether the protection officers are being paid for privately, or by taxpayers.

Earlier this year it was announced that Meghan's armed Scotland Yard bodyguard, who accompanied the expectant mother on her royal tour of Australia with Prince Harry last year, was quitting her post after less than a year in the role.

The inspector's appointment as head of protection made her the first woman to hold such a key post for the royals, and she was regularly pictured guarding Meghan on overseas trips.

In January, it was revealed that protection officers tasked with guarding the Queen and other members of the royal family earned six-figure salaries in 2016/17, bringing in around $130,000 (£100,000) each, after winning a pay dispute with Scotland Yard over their 'special escort' allowance.

The latest accounts for the Metropolitan Police show 47 officers from the Royalty and Specialist Protection (RaSP) unit earned six-figures in 2016/2017. This is in addition to the large one-off payments given to officers after the dispute over the scrapping of escort allowance in 2012.

The Met has not disclosed the exact payments, but at least £5 million was paid out among the 47 officers, which works out at as an average of $137,512 (£106,383) each.

No show: Meghan's friend Priyanka Chopra all but confirmed that she would not be attending the shower when she posted this image of herself on Instagram on Tuesday afternoon, and tagged the location as Beverly Hills, California

Her hands are full! Pilates instructor Heather Dorak, another friend who attended the royal wedding, welcomed a child on Valentine's Day, which presumably left her unable to attend the shower

The visit marks the first time the Duchess of Sussex has been in the Big Apple since she said 'I do' to Prince Harry in May 2018, and she wasted no time before visiting some of her favorite hot spots.

Sources confirmed to Harper's Bazaar that friends are throwing Megan a baby shower at an undisclosed Upper East Side hotel for 15 guests on Tuesday, the day before she leaves.

Jessica Mulroney, Meghan's close friend and unofficial stylist, is thought to not only be attending the shower, but also helping to spear-head the organization of the intimate event. The GMA fashion expert is also thought to have had a hand in helping Meghan with the planning of her wedding to Prince Harry.

Although no other members of Meghan's inner circle confirmed any details about the shower, sources have told Harper's Bazaar that the royal wanted the opportunity to spend time with her closest friends in one of her favorite cities before the birth of her first child, which is due in just a matter of months.

'The trip is a lovely chance to catch up with friends and spend time in a city she loves,' a source told the outlet.

'This will be the last time a lot of them will see Meg until after the baby is born so it’s nice to share precious moments.'

But while the trip may have come as a surprise to some, according to the unidentified friend of the royal's, Meghan's visit to the Big Apple was actually planned months ago.

'It’s been a relaxing visit. Nothing beats face time with your friends,' the person added. 'Meg will be flying home refreshed and relaxed - and with a lot of new baby clothes.'

Meghan joined Jessica at Ladurée in SoHo on Saturday to enjoy macarons and tea in one of the location's private spaces, according to Harper's Bazaar.

Although Jessica is based in Canada, she arrived in New York late last week to film some style segments for Good Morning America, after being named the show's newest fashion contributor in late 2018.

Way back when: Meghan Markle once did a photo shoot for fashion brand Tod's in the ornate French restaurant

Big Apple fun: A source said the trip is a chance for Meghan to 'catch up with friends and spend time in a city she loves.' The former actress is pictured in New York City in 2016

Royal return: The visit marks the first time Meghan has been in the Big Apple since she said 'I do' to Prince Harry in May 2018. The couple is expecting their first child this spring

The decision to visit Ladurée may well have been Meghan's however, as the known foodie once took part in a photo shoot for Tod's in the ornately decorated French restaurant.

In an image from the shoot, she is seen sitting in the New York tourist hotspot, wearing a patterned suit, a white shirt, and a pair of silver Tod's loafers with fringing detail on the front.

Her makeup for the shoot was rather more glamorous than the subtle, natural looks she seems to prefer now; in the photo, Meghan can be seen modeling a bright pink lip, and dark, smokey eyes, while staring right into the lens with a very serious expression on her face.

But it seems the somewhat unimpressed look she was making in the shot does not reflect her feelings about the French eatery, which is famed for its colorful confections and wide variety of teas, as well as its elegant interior.

The Duchess also praised the restaurant in an interview with writer Barry Samaha.

'I love Ladurée in SoHo,' she said. 'It’s like a little slice of Paris in the middle of New York City.

'It is absolutely beautiful, and the courtyard is awesome,' she added. 'Everyone should get the Coupe SoHo, which is this amazing salted caramel ice cream. It’s delicious!'

And it's not just Ladurée that holds a special place in Meghan's heart; the Duchess spoke on a number of occasions about her love for New York City and its many restaurants, bars, hotels, and shops, even giving the website Citiphile a full rundown of her favorite spots back while she was still starring as Rachel Zane in Suits.

During the interview with the site, Meghan referenced several much-loved New York establishments, including the Marlton Hotel, Italian eatery Babbo, piano bar Marie's Crisis, and West Village favorite Fedora - which she praised for its dirty martinis.

But according to sources, when Meghan isn't indulging in pastries from Ladurée, she will be spending much of her time enjoying the many amenities at the undisclosed five-star hotel where she is believed to be staying for the duration of her trip.

The day before she flew to New York, Meghan enjoyed a quiet Valentine's Day evening with Prince Harry, their first as a married couple.
