In 2008 Newsom married Jennifer Siebel, a filmmaker. The couple have four children. Newsom was previously married (2001–05) to Kimberly Guilfoyle, a lawyer who was then working in the district attorney’s office in San Francisco. She later became a TV personality. In a 2004 feature in Harper’s Bazaar magazine, Newsom and Guilfoyle were dubbed “the New Kennedys,” a reference to former U.S. Pres. John F. Kennedy and his wife, Jackie Kennedy. They divorced, however, the following year. Guilfoyle later attracted attention for her work on the conservative Fox News Channel.
