A second Newsom is on the way, folks. Leah Garchik has the scoop.

And on Masonic Street, there's reason for the Newsoms to rejoice (having nothing to do with Larry Ellison). Raise your Christmas Eve glasses tonight to toast Jennifer Siebel Newsom, Gavin Newsom, and baby Montana, who'll become a big sister in June. I'd made some inquiries about this a few months ago, but the first family was shy about it until late Wednesday, when Siebel Newsom called with confirmation. Thursday, mayoral evasion on the issue led Ronn Owens to figure it out.

The baby-in-the-making is a boy, and his due date is June 19, which is Siebel Newsom's birthday. The family plans to keep on living here, in the Upper Haight, while the new lieutenant governor commutes to his job in Sacramento.

An heir to the Newsom throne? Delightful.

Congratulations to the entire Newsom family.
