It was the biggest night in the British music industry's calendar.

So it's no surprise some of the stars who attended the BRIT Awards and its afterparties were left feeling - and looking - slightly worse for wear at the end of the night on Wednesday.

Leaving the array of post-show soirees, likes of Ed Sheeran, Sinitta and Charli XCX were certainly among the worst hit after perhaps having a little too much to drink.

BRIT behaving badly: Ed Sheeran celebrated raucously after winning two awards at the BRITs on Wednesday night, looking more than a bit worse for wear as he left the afterparty later on

Double BRIT winner Ed had clearly spent most of the night celebrating hard, as he was held up by one of the members of his security team as he went from one party to another.

Despite his ungainly state, he managed to go on to The Box nightclub in central London, where he proved his status as a true, party-hard Brit, staying there until six in the morning.

Earlier in the evening when picking up one of his awards, he admitted to the show's hosts Ant and Dec that he would be indulging in a tipple or several.

'I've got to perform and then I'll drink. Don't film me later!' he quipped.

Life and soul: Earlier on at the post-show bash, the singer had kept his friends and entourage entertained

Helping hand: But it wasn't long until he needed to be given a bit of a lift as he left the party

Careful: The waistcoat-clad star didn't look too comfortable on his feet

The ginger-haired singer, 24, had spent the evening raising glasses with his colleague and fellow BRIT winner Sam Smith.

And the soulful singer, 22, was left with Ed sitting on his lap in their taxi as they were whisked away to their next event.

Ed had bagged himself the British Male Solo Artist gong, and also the British Album Of The Year, while Sam took home the Global Success and British Breakthrough awards, so they were certainly in the mood to let their hair down.

Also looking as though the night of dancing, drinking and mingling with fellow showbiz types became a bit too much was singer Sinitta.

Slinking out: He was joined by friend and fellow BRIT winner Sam Smith as they made their way to go to another party late in the night

Buddies: Ed and Sam looked rather cosy in the back of the car as they were whisked off to The Box in central London, where they carried on partying until 6am

What's up? The talented singers appeared distracted as they went to leave

So over it: Ed tried to maintain his composure as he leant forward in the back of his cab, but he had clearly passed the point of no return

The 51-year-old may not technically be British but after living in the United Kingdom for much of her life she sure knows how to let her hair down like a Brit.

The singer was seen emerging from the Sony Music afterparty at Sushi Samba, looking as flawless as ever.

But when she got into her car, she bore the telltale signs of somebody who had perhaps revelled a little too hard, holding her hand against her face as she appeared ready to go to bed.

She also proved that she didn't care as she reclined in the back of the car with her feet up on the front seat.

Meanwhile Marina Diamandis, of Marina And The Diamonds, couldn't hold her composure as she departed from Warner Music's afterparty, held at Freemasons' Hall in the capital.

Feeling the effects: Sinitta may not be British, but she proved her worth as an honorary Brit after partying hard on Wednesday night

Chilling out: As the 51-year-old singer was escorted away from Sushi Samba, she put her feet up on the front seat of the car while looking ready to fall asleep

Good spirits: She managed to look collected as she left the bash, flashing her taut abs for all to see

Got a headache? But she grimaced too, unable to hide the fact she may have been suffering with a bit of a painful head

Although she still cut a stunning figure, wearing the beautiful glitzy floor-length gown she had worn to the BRIT Awards ceremony earlier in the evening, she revealed her dishevelled state as she dropped her bag all over the floor.

The 29-year-old looked embarrassed as items from her bag were left laying on the pavement.

Her phone - now perhaps the victim of a smashing - laid on the ground, along with her keys, a cigarette packets and items of make-up.

She quickly crouched down to the ground to retrieve her personal belongings before scuttling off.

Whoops! Marina Diamandis left the Warner Music party in good spirits and looking glam, but she dropped her bag and its contents all over the ground

Who's going to pick it up? The star seemed to maintain her stance as she appeared to be asking for someone else to grab her items

Oh dear: The singer - better known as Marina And The Diamonds - had dropped her phone to the road

The crouch of shame: She eventually bent down to pick up her items in a hurry

And she was clearly feeling the effects of her heavy evening out as she posted a message on Twitter on Thursday morning, declaring her need for greasy food.

'I need fried cheese,' she wrote.

Marina's pal Charli XCX couldn't hide her tousled appearance as she was seen leaving the Warner Music post-show bash slightly later on.

The 22-year-old Fancy hitmaker threatened to reveal too much of her chest as she stepped out in a dress with a sheer panel, the portion underneath slipping down dangerously low.

She's not so Fancy: Charli XCX staggered Bambi-like out of the Warner Music afterparty

Chatty star: The 22-year-old appeared to be in full conversation mode with her friends, who helped her out

'Classic': The British star - who almost revealed too much under her sheer top - posted on Instagram the following morning that it had been a 'classic' night

The musician initially appeared embroiled in an animated conversation with her friends, but she quickly slipped into the depths of drinking hell as she put her hand over her face and her eyes closed as she made her way to leave.

She staggered her way out of the venue, looking decidedly Bambi-like in her heeled shoes, her brunette locks falling messily over her face.

And the following morning, the humorous star shared a picture of herself looking less-than-glamorous from her drunken state writing 'classic' alongside it.

Millie Mackintosh is usually known for her demure elegance at the wide array of showbiz parties she attends, but even she felt the burden of a night of drinking after the BRITs.

Although she had seemed composed all evening, the 24-year-old beauty was whisked away at the end of the evening in her car, leaning forward onto her hands, seemingly on the verge of falling asleep.

Holding it in... just: She looked ready to expel the night's drinks as she got into her car

Bedtime: In the small hours of the morning, she was gladly whisked off home

Tottering: Millie Mackintosh failed to maintain her usually-demure aura as she left the party on the arm of a friend

Nope: The former Made In Chelsea star didn't feel so great as she fell asleep in the back of her car
