interesting excerpts:
Several months ago, Guilfoyle Newsom herself told family and friends she had "never signed on" to be a mayoral wife – something others found hard to believe, given the high-profile and politically tinged wedding the couple staged for 500 people at St. Ignatius Church in December 2001. The guest list for the wedding and subsequent reception at the home of Ann and Gordon Getty included dozens of political consultants, campaign managers and the media, and many saw it as the unofficial launch of then-Supervisor's Newsom's mayoral campaign.
Guilfoyle Newsom was then working as a prosecutor for District Attorney Terence Hallinan, where she had drawn notice during the murder trial of the couple accused in the dog-mauling death of Diane Whipple. Soon the former lingerie model landed a job with Court TV, and not long after Newsom was elected mayor in December 2003, she took off for New York. …
In August, Guilfoyle Newsom started a gossip firestorm with a photo spread she arranged in Harper's Bazaar that featured the couple posing on a rug, on the floor of the Getty mansion no less. She made news again a couple of months back when she joked at a gay rights benefit in New York about Newsom being well "hung."
