Adam Brody and Leighton Meester Welcome Baby Girl ‘Arlo’!

Leighton Meester and Adam Brody’s baby girl has arrived…and now we know what they named her.

Although the couple is super private, it was revealed that they welcomed a daughter Tuesday, Aug. 4 in Whittier, Calif., with People reporting that her name is Arlo Day Brody.

Leighton and Adam are so private that they actually never confirmed the pregnancy or the birth themselves. They also have never talked to the media about their marriage or wedding after tying the knot in early 2014.

Little Arlo might be in for some awesome play dates, though, considering Leighton’s former Gossip Girl costar Blake Lively welcomed a baby girl last December. Fans of the show were swooning over the thought of just that, tweeting away about the possibility of a mini Gossip Girl squad.
