Who Is Kimberly Guilfoyle, Gavin Newsom’s Ex-Wife?
Kimberly Anne Guilfoyle was born on March 9, 1969, in San Francisco. She is American. Her father is of Irish descent, and her mother, Mercedes, was born in Puerto Rico. Guilfoyle has often spoken about her mixed heritage and about growing up in the Bay Area, where she was raised in a working family.
She went to college at the University of California, Davis, and graduated in 1991 with a bachelor’s degree in history. She then studied law at the University of San Francisco School of Law and earned her law degree in 1994.
After law school, she went straight into public service. She joined the San Francisco District Attorney’s office as a prosecutor and built a reputation in the courtroom. That reputation led to invitations to comment on legal cases on television. Her time in the DA’s office and her growing media profile set the stage for everything that followed, including her marriage to a rising city politician.
Kimberly Guilfoyle’s Career: From Prosecutor to Ambassador
Guilfoyle’s career has had several distinct chapters.
Law and legal commentary. She started as a San Francisco prosecutor. Her skill on camera then took her to Court TV, where she worked as a legal analyst.
Fox News. In 2006 she joined Fox News and became one of its best-known faces. From 2011 she co-hosted the afternoon talk show The Five. She left the network in 2018.
Politics. After Fox, she moved into Republican politics. She became a senior fundraiser and campaign adviser in President Donald Trump’s political orbit. She also gave a prominent speech at the 2020 Republican National Convention.
Diplomacy. In 2025 she became U.S. Ambassador to Greece. She was sworn in at the State Department on September 29 and became the first woman to hold the post. She officially took office in Athens later that year.
Her time as ambassador ended abruptly. She stepped down on October 13, 2026, after the White House asked for her resignation over allegations of improper conduct at the embassy. She said she would vigorously defend herself against the allegations, which she called false. The matter is still developing, so check recent reporting for updates.

How Did Gavin Newsom and His Ex-Wife Kimberly Guilfoyle Meet?
Newsom and Guilfoyle met in San Francisco in the late 1990s. At the time, Newsom was a local businessman turned member of the Board of Supervisors, and Guilfoyle was a young prosecutor. Both were ambitious and well known in city circles, and the press soon treated them as one of San Francisco’s glamorous power couples.
They dated for a couple of years before getting engaged. Their relationship took place during a period when both of their careers were taking off. Newsom was gaining attention as a political leader, and Guilfoyle was becoming a recognizable legal voice in the media. The attention that came with being a “power couple” was part of their public story from the start.
They married in December 2001. Newsom was elected mayor of San Francisco in December 2003, and Guilfoyle became the city’s first lady while keeping her own career going.
Marriage and Divorce: Gavin Newsom Ex Wife Timeline
The wedding took place in December 2001, and it drew significant local attention because Newsom was already a rising figure in city politics.
The marriage did not last long. In January 2005, the couple announced that they were separating. They explained that the demands of their separate careers were pulling them apart. Guilfoyle had moved into television work that took her to New York, while Newsom was busy running San Francisco. The divorce was finalized in 2006.
Neither of them made the split a public fight. Newsom has spoken about it only occasionally, and Guilfoyle has largely moved on in public, though the two have remained on opposite sides of the political divide. The marriage lasted roughly four years in total, counting from the wedding to the separation.
Newsom went on to marry Jennifer Siebel Newsom in 2008. Guilfoyle later married Eric Villency in 2006, a marriage that ended in divorce in 2009.

Newsom and his wife Jennifer Siebel Newsom have four children, and Newsom has often talked about fatherhood in his public life.
After her second divorce, Guilfoyle’s best-known relationship was with Donald Trump Jr. They became a couple around 2018 and later got engaged. NPR described it as a lengthy engagement that ended before her ambassador role came to an end. Guilfoyle has said she values keeping her family close despite living in the public eye and traveling often for work.
Kimberly Guilfoyle on Social Media
Guilfoyle is active on social media, especially Instagram and X, and her accounts have drawn a large following over the years. Her posts have covered politics, her appearances at events, travel, and personal moments with her family.
