OK. Here we go. Jennifer Siebel Newsom is in labor. Gavin Newsom, via Twitter, says:

Eee!

The city's newest citizen, a Virgo girl, is just minutes (or hours) away. We'll update as soon as we know more.

Update: Catherine Bigelow and Appeal have word that the little blessing, named Montana Tessa Newsom, weighed in at "a healthy 7 lbs. 12 oz. and 20.5 inches ... born at 12:39 p.m." Ta-da. And here, courtesy of Christopher Renstrom, is Monty's very first horoscope: " The New Moon in Virgo makes you even more determined to beat a problem. Willpower plus mental acumen gets results! "

Congratulations, Newsom family. Now get to swaddling and diaper changing, you two.
