Controversial San Francisco mayor Gavin Newsom and C-List actress Jennifer Siebel became engaged over the weekend in Hawai’i according to mutual friend Stanlee Gatti.

One of Newsom’s closest friends, high society party planner Stanlee Gatti, confirmed the engagement. “Jennifer told me (about it). She was on the phone first, and then he got on the phone,” said Gatti, reached in Raton, N.M., where he was on vacation.

The couple met on a blind date at the Artists Ball at Yerba Buena Center in October 2006. Mutual high-society friend Kathy Wilsey set up the meeting. The theme was “Stanlee’s Brain,” a spoof on Gatti, one of high society’s most sought-after party planners known for his extravagant stagings.

It will be the second marriage for Newsom and first for Siebel.  Newsom’s first marriage to TV correspondent Kimberly Guilfoyle ended in divorce after his deputy chief of staff, Alex Tourk, resigned after discovering that Newsom had been having an affair with his wife, Ruby Rippey-Tourk.

Mayor Newsom rose to fame in 2004 when he issued an illegal directive to the city/county clerk to issue marriage licenses to same-sex couples.

Siebel’s acting career has landed her in several movies and TV shows including In the Valley of Elah, ‘Life’, Rent, ‘Numbers’, and Till You Get to Baraboo.
