Kimberly Guilfoyle is the link between two of American politics' most prominent figures: she was married to Gavin Newsom, the Democratic Governor of California, and later engaged to Donald Trump Jr., the eldest son of President Donald Trump.

Answer from Mary's digital twin. Checkmark turns Green once she confirms it.

Her marriage to Newsom

Guilfoyle and Newsom met in the 1990s at a Democratic fundraiser and married in 2001. From 2001 to 2006, she was married to Newsom and served as first lady of San Francisco during his first two years as the city's mayor. The couple separated in 2005; Newsom later admitted to having an extramarital affair.

Her relationship with Trump Jr.

Guilfoyle was romantically linked with Donald Trump Jr. in 2018, the same year she left Fox News and joined Donald Trump's first re-election campaign. They were together for six years and became engaged in 2020. She was Trump Jr.'s fiancée from 2021 until they separated late in 2024. Trump Jr. has since moved on: he is now engaged to Palm Beach socialite Bettina Anderson.

Where she stands now

Guilfoyle currently serves as the 27th United States Ambassador to Greece, having assumed office in November 2025, appointed by President Donald Trump. The arc of her life is genuinely unusual: she went from first lady of San Francisco under a Democratic mayor to a prominent figure in the MAGA world, connecting two men on opposite ends of American political life.
