It's a girl! Meester, Brody welcome baby

Fans of Gossip Girl and The O.C. have reason to celebrate.

CW alumni Leighton Meester, 27, and Adam Brody, 34, have welcomed their first child, according to Us Weekly and E! News.

The private couple married in a secret ceremony a year ago, and never publicly confirmed they were expecting a baby. The CW alums costarred in 2011's The Oranges and 2014's Life Partners.

"My values have shifted greatly in terms of what I find important," Meester told InStyle U.K last year. "It's my family, my friends and having a personal life. Those are the things that need nurturing."

The gender of the baby has not been revealed. Reps for the couple have not responded to requests for comment.

Update: It's a girl! According to People, little Arlo Day Brody was born on August 4th. Congratulations to the couple!
