Jennifer Siebel and Mayor Gavin Newsom ride in San Francisco's gay pride parade June 29.

San Francisco Mayor Gavin Newsom took a break from his busy job and gubernatorial ambitions to marry actress Jennifer Siebel on Saturday at Siebel's parents' Montana ranch.

It was the 34-year-old Siebel's first marriage and the second for Newsom, who divorced legal analyst Kimberly Guilfoyle in March 2006.

Newsom met Siebel in October 2006, and they have been together ever since. Siebel was at Newsom's side when he was sworn in for his second term as mayor in January. She also stood by him after he publicly admitted to having had an affair with a staff member's wife and a drinking problem.
