(AP) SAN FRANCISCO -- San Francisco Mayor Gavin Newsom and his wife, actress Jennifer Siebel Newsom, are celebrating the birth of their first child -- a 7 pound, 12-ounce girl.
Montana Tessa Newsom was born at 12:39 p.m. today in San Francisco.
The baby was named after the state where the couple wed in 2007 and the mayor's late mother.
Nathan Ballard, Newsom's spokesman, says mother and daughter are doing well.
The 41-year-old Newsom, who is in his second term as mayor, is seeking the Democratic nomination to succeed California Gov. Arnold Schwarzenegger next year.
Newsom announced his candidacy on Twitter and kept up the trend by sending tweets from the hospital maternity ward.
He wrote, "Jen doing great...Not sure she is happy I am on twitter."
