The mayor’s spokesman, Nathan Ballard, said the mayor popped the question Saturday.

“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.Gatti had no details about the proposal, other than Newsom spoke with his girlfriend’s father first and then proposed marriage. No wedding date has been set, Gatti said.

It will be the second marriage for Newsom, 40, one of the Bay Area’s most eligible bachelors, and the first for Siebel, 33.
