It looks like Donald Trump Jr.'s rumored new girlfriend Kimberly Guilfoyle will be a perfect fit as far as his family is concerned, at least when it comes to getting on with his stepmother, Melania.

While on the surface, the two women might appear to have nothing more in common than their long brunette locks, high cheekbones, and statuesque figures, but at a closer glance, Kimberly, 49, bears many remarkable similarities to the first lady — certainly more than Don Jr.'s estranged wife, Vanessa.

First of all, Kimberly is political royalty in her own right; she served as the first lady of San Francisco when her former husband, Gavin Newsom, was mayor. The co-host of The Five is also just a year older than Melania, and they both got their starts in modeling before becoming public political figures.

Kimberly was born and raised in San Francisco and grew up in what SFGate described as a 'decidedly working class' background.

Her father, Anthony Guilfoyle, is an Irish immigrant who did construction work and served in the military before becoming a real estate investor. Her mother, Mercedes, moved from Aguadilla, Puerto Rico, and taught special education. She died of leukemia when Kimberly was 10.

'My mother was just everything to me, I loved her so much, I always wanted to be around her. I loved how I saw people react to her,' she told Mediaite in 2015.

'She was a warm woman who worked in education with people with emotional challenges. I got my sense of giving back and how when you have many blessings, pay it forward.'

Melania, who was born in Slovenia, came from a similar working class background. Her father, Viktor Knavs, was a car dealer, and her mother, Amalija, designed children's clothing.

The first lady sponsored her parents' move to the United States, and Michael Wildes, a New York-based immigration lawyer who represents the first lady and her family, told the Washington Post in February that the Knavses are living in the country on green cards.

There have been claims that Melania obtained a degree from University of Ljubljana; however, CBS News reported that she only attended the school for a year before returning to modeling.

Although Melania thrived as a model, Kimberly told SFGate in 2001 that, for her, modeling 'was a means to an end, period'.

Don Jr.'s alleged new love interest modeled swimsuits and lingerie just like his stepmother did, but she opted to use her earnings to attend law school after graduating from the University of California, Davis.

'I knew I wanted to go to law school and it ended up being a great way to pay for it. I modeled everything from clothes, swimwear and lingerie, including Victoria's Secret!' she told People in 2014.

'I met an incredible number of interesting people through modeling and really learned a lot about self-confidence and self-worth.'

Her decision to make money as a model certainly paid off in more ways than one; Kimberly received her Juris Doctor (J.D.) from the University of San Francisco School of Law in 1994.

Having had relatively modest upbringings, Kimberly and Melania are both drawn to powerful, wealthy men.

Melania famously met Donald Trump at a Fashion Week party in 1998 when she was just 28 years old.

She is said to have refused to give the then 52-year-old real estate mogul her phone number because he was with a date, but she ended up calling him a few days later.

But it wasn't until 2005 that the former model became Trump's third wife, when they said 'I do' at their lavish Palm Beach wedding.

Kimberly, meanwhile, dated oil tycoon Billy Getty before starting her relationship with Gavin, whose father, William Alfred Newsom III, is an administrator of the Getty family trust.

She wed Gavin, then a city supervisor, in 2001, and two years later he was elected the mayor of San Francisco. He is now the lieutenant governor of California and currently running for governor of the state.

Like Melania, Kimberly knows a few things about hosting foreign dignitaries.

As the first lady of San Francisco, she and her former husband welcomed Prince Charles and his wife Camilla, the Duchess of Cornwall, on their first official visit to the city during their U.S. tour.

'I spent three days with them and it was a wonderful experience,' she told People in 2014. 'During one of the formal dinners, I was sat next to Prince Charles who was kind enough to share the rest of his apple tart dessert with me.'

In addition to her role as first lady, Kimberly served as San Francisco's assistant District Attorney from 2000 to 2004 before moving to New York City to pursue a career in television. Kimberly and Gavin's bi-coastal relationship put a strain on their marriage, and she filed for divorce in 2005.

In 2006, the same year she joined Fox News, Kimberly married furniture heir Eric Villency, the CEO of Villency Design Group. They welcomed their son, Ronan Anthony, in October 2006, less than five months after they said 'I do.'

Second husband: After divorcing Gavin, Kimberly married furniture heir Eric Villency, the CEO of Villency Design Group in 2006. They divorced three years later.

Single mom: Kimberly and Eric's son, Ronan, was born in October 2006, less than five months after they said 'I do'

Only children: Melania's son, Barron Trump, 12, is just a little over six months older than 11-year-old Ronan

Not only are Kimberly and Melania just a year apart, their only sons are around the same age as well. Barron Trump, 12, is just a little over six months older than 11-year-old Ronan.

However, unlike Melania, Kimberly is a single mom. She and Eric announced their separation in 2009 and eventually divorced.

The Fox News host, who has repeatedly defended the Trump family on-air, was rumored to have dated Anthony Scaramucci last year.

Kimberly confirmed last year that she had been in contention to serve as Trump's press secretary. She reportedly turned it down and extended her contract with Fox.

She and Don Jr., 40, run in the same New York City social circles, and she has hobnobbed with both him and his estranged wife, Vanessa, a former model-turned-mother-of-five.

Vanessa, 40, filed divorce papers in Manhattan Supreme Court in March after 12 years of marriage to Don Jr.

The divorce was listed as 'uncontested,' meaning Vanessa is not asking for full custody of the children and Don Jr. does not object to the filing.

'After 12 years of marriage, we have decided to go our separate ways,' the pair said in a joint statement.

'We will always have tremendous respect for each other and our families. We have five beautiful children together and they remain our top priority. We ask for your privacy during this time.'

Lawyers for Trump's eldest son have since asked the court for a statement on Vanessa's net worth after it was revealed she inherited millions from her father's investment in Rao's marinara sauce.

Don Jr. has been dating Kimberly for a few weeks, sources told Page Six.

One source said the they are 'seeing each other' and 'having a great time.'

'While he wants to respect the privacy of his family, he is getting divorced, and he enjoys Kimberly's company,' he person added.

Don Jr. and Kimberly were recently seen arriving together at a party in honor of Richard Grenell, Trump's new ambassador to Germany.

Sources said the couple 'stuck close to each other' at the party on Sunday and left together to grab dinner at the upscale Harry Cipriani restaurant in Manhattan.

Three may be a lucky number for the Trumps.

Melania is the president's third wife, and if Don Jr. and Kimberly were ever to get married, he would be her third husband.
