Who is Kimberly Guilfoyle? Fast facts and biography of TV presenter and attorney Kimberly Guilfoyle, who recently became official with Donald Trump, Jr.

From summers in her father's native Ireland to a major law career to San Francisco's first lady, here's everything you need to know about Kim Guilfoyle.

Who were Kimberly Guilfoyle's parents and where were they from? 

Kimberly Ann Guilfoyle was born March 9, 1969, in San Francisco to Mercedes Marie Gerena from Puerto Rico and Anthony Guilfoyle from Ireland. 

Her mother was a special education teacher and a major inspiration for young Kimberly. She tragically passed away from Leukemia when Guilfoyle was 11. As the said in a 2015 interview with Mediaite

"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 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."

Her father, Tony, immigrated to the US from Ennis, Co. Clare in his 20s in 1957 and served for four years in the US army, from 1958 - 1962. He then got into construction and became a real estate investor. 

He passed away in 2008, and Guilfoyle has spoken profoundly about the lessons he taught her, along with her mother:

“My late father Anthony Guilfoyle left Ireland in his twenties and went to work in America. He worked in construction in San Francisco and later became a contractor and political adviser. He was drafted into the US Army and stationed in West Germany. My mother, Mercedes, was a special needs teacher who died when I was a child. My parents worked hard to ensure we had a better life. They supported us and gave us the courage to pursue our dreams. I appreciate that greatly. My father was so proud of my achievements.”

She has a big love for Ireland and spent summers working there as a teen

Guilfoyle returned to her father's native town of Ennis every summer, working in her family’s local store.

“I grew up partly in Ireland,” she's said.

“Every summer from the age of five, I lived in Ennis where my Guilfoyle relatives had businesses on O’Connell Street — a gift shop called Dalcassian House, and Dalcassian Printers. I worked in the shop, which sold lovely china and Waterford Crystal.

“I was about 11 or 12 and I got about IR£10 a week. It instilled a sense of responsibility in me, putting in the hours and earning the money."

She stayed in Ireland to study law at Trinity College Dublin. While there, she published research in international children's rights and European Economic Community law.

She began her law career as a prosecutor in San Francisco and worked as an attorney before switching to television

Guilfoyle was a public prosecutor in San Francisco, worked as Deputy District Attorney in Los Angeles, and then returned to San Francisco as Assistant D.A. until 2004.  

In that same 2015 Mediaite interview to mark the publication of her book Making the Case, she explained her drive to become a prosecutor was inspired by the loss of her mother: 

"I became a prosecutor because I got my greatest joy in working with victims of violent crimes. I understood that profound sense of loss, and I could relate to it, and I wanted to do anything to help them heal by seeking justice. Wanting to make sure the person who wronged them or their family, that there would be closure. It’s so hard when you have a family member pass away, like cancer, it’s debilitating. But are you going to be mad at cancer? No."

In 2004, she decided to embark on a television career, moving to New York. She started out on Court TV and as a legal analyst for Anderson Cooper 360, and then moved to Fox in 2006, where she's been since on a number of shows including The Lineup, The Five, and as a guest host on a number of other regular programs. 

She was married to Gavin Newsom, the (Democratic!) mayor of San Francisco

Guilfoyle and Newsom wed in 2001 when he was a city supervisor. He was elected mayor in 2003, shortly before Guilfoyle left for her new job in New York.

They divorced in February 2006, citing the pressures of a bi-coastal relationship, but she was San Fran's first lady for two years. The local media there has enjoyed speculating about how surprising it is to see her involved with the Trump administration now, and how Newsom, now Lieutenant Governor of California, is one of its most outspoken critics. 

Guilfoyle has a 12-year-old son with her second husband

She and Eric Villency wed in May 2006, and their son, Ronan Anthony - very Irish names for her father - was born October 2006. 

Villency and Guilfoyle announced that they were separating in 2009 and then legally divorced. 

Donald Trump, Jr and Kimberly Guilfoyle made their relationship official in June

Guilfoyle has been linked to Don Jr. since shortly after the eldest first son’s official split from his wife in March 2018. While the pair was spotted together following President Trump’s State of the Union address in January 2018, which Guilfoyle was covering for Fox, the relationship is believed to have started after Don’s estranged wife Vanessa filed for divorce. Since the split, it had been revealed that Don Jr had an affair with Aubrey O’Day.

He and Vanessa split this year after 13 years of marriage. The couple has five children together; Kai (10), Donald III (9), Tristan (7), Spencer (5) and Chloe (3).

Trump Jr and Guilfoyle went public with their relationship in late June when they appeared in Montana together as Trump was to speak at the state's Republican convention in support of Senate candidate Matt Rosendale.

"Just as everyone else thanks their significant others, I got to thank Kimberly for coming out here. We're going to take her fishing tomorrow, then shooting," he told the crowd, according to Vanity Fair.

Just two weeks later, they spent their first July 4th together in the White House, Guilfoyle’s first official Oval Office event as the First Son’s girlfriend.
