How Gavin Newsom and Kimberly Guilfoyle Met and Fell in Love
Gavin Newsom and Kimberly Guilfoyle first crossed paths in the mid-1990s at a Democratic fundraiser in San Francisco. At the time, Guilfoyle was a sharp, driven prosecutor working in the district attorney’s office, while Newsom was rising through local politics as a city supervisor.
Guilfoyle later described the moment she noticed him: tall, charismatic, and full of energy. Their connection grew over the years, blending shared professional circles with personal chemistry. After dating for several years, they tied the knot in December 2001 at St. Ignatius Catholic Church in San Francisco, followed by a lavish reception at the Getty mansion.
The couple quickly became a media darling. In 2003, when Newsom was elected mayor of San Francisco, Guilfoyle stepped into the role of First Lady. They were often compared to a modern-day power couple, with media outlets dubbing them “the New Kennedys” in a glamorous 2004 Harper’s Bazaar spread.
Here are a few highlights from their early years together:
- Shared spotlight: Guilfoyle supported Newsom’s initiatives while balancing her own career as an assistant district attorney.
- High-society events: They attended elite gatherings and were seen as symbols of San Francisco’s vibrant political scene.
- Public image: Their marriage projected youth, style, and progressive values.
It seemed like a perfect match—at least on the surface.
The Glamorous Yet Short-Lived Marriage
During Newsom’s early tenure as mayor, Guilfoyle served as First Lady of San Francisco from 2004 to early 2006. She was elegant, outspoken, and deeply involved in public life, often appearing at charity events and supporting local causes.
However, cracks began to show. The demands of their careers created strain. Guilfoyle took on opportunities in New York, leading to a bicoastal marriage that proved challenging. In January 2005, the couple jointly announced their separation, citing “the demands of our respective careers” in an official statement. They emphasized they would remain close friends.
Their divorce was finalized on February 28, 2006. Newsom later reflected on the relationship in his memoir Young Man in a Hurry, describing moments of emotional distance and admitting the union sometimes felt like “going through the motions.” He also acknowledged personal mistakes during that period, including an extramarital affair that became public later.
Despite the end, both parties described the split as relatively amicable compared to many high-profile divorces.
Life After Divorce: Two Very Different Paths
After the divorce, Kimberly Guilfoyle’s life took a sharp turn toward media and conservative politics. She built a successful career as a legal analyst and Fox News personality, becoming a familiar face on national television. She later married furniture heir Eric Villency in 2006 (they had a son, Ronan, and divorced in 2009). For years, she was in a high-profile relationship with Donald Trump Jr., which ended in late 2024.
In a notable development, Guilfoyle was appointed U.S. Ambassador to Greece in 2025 and continues to serve in that diplomatic role as of 2026, representing American interests from Athens.
Gavin Newsom, on the other hand, moved forward personally and politically. He married documentary filmmaker Jennifer Siebel Newsom in 2008. The couple has four children and has built a strong partnership, with Jennifer serving as First Partner of California and advocating for gender equality and women’s issues.
Newsom has gone on to become one of the most influential Democratic governors in the country, often in the national spotlight.

What Their Story Teaches Us
The journey of Gavin Newsom’s first wife highlights how personal and professional ambitions can align beautifully at one stage of life and pull people in opposite directions at another. What started as a promising political romance in liberal San Francisco evolved into two individuals carving out very different legacies—one deeply rooted in Democratic leadership, the other in conservative media and now diplomacy.
It’s a reminder that relationships, especially in the public eye, are complex. Careers, personal growth, and timing all play huge roles. Today, both Guilfoyle and Newsom appear to have found paths that suit their evolving priorities, and their past connection remains a curious footnote in California political history.
Whether you’re interested in politics, celebrity relationships, or just love a good real-life story, the tale of Newsom and Guilfoyle offers plenty to think about. Ambition can bring people together—and sometimes gently (or not so gently) push them apart.
