Kimberly Guilfoyle Newsom was born in San Francisco to a Puerto Rican mother and an Irish-American father. Her mother died of leukemia when Kimberly was ten, and she and her younger brother were raised by a single father. Kimberly worked her way through college and law school, including a brief stint as a lingerie model, before becoming an assistant district attorney in San Francisco. She received national attention in 2001, when she successfully prosecuted two defendants whose dogs had mauled a woman to death in San Francisco. That same year, she married Gavin Newsom, a city supervisor from a prominent family; he was elected mayor in 2003. Kimberly is extremely visible in San Francisco society, as a member of many charitable organizations, and maintains close ties with the Getty family. In 2004, she moved to New York to become a legal consultant for MSNBC, CNN and CourtTV. In January 2006, Kimberly joined Fox News Channel where she is host of The Lineup (2005). She is also a legal analyst for the Fox News Channel.
