Leighton Meester and Adam Brody Welcome First Child: Report

And baby makes three.

Well, four, if you count Leighton Meester’s adorable dachshund. We’ll talk about her later…

Us Weekly is reporting that the 29-year-old is officially a mother. Meester and her husband Adam Brody, 34, welcomed their first child last week. No further details, including the baby’s gender and name, are known at this time.

News of Meester’s pregnancy first broke in the spring when the former Gossip Girl star was spotted with her baby bump in Los Angeles. Meester and Brody have been married since February 2014. The couple tied the knot in a private ceremony some three years after meeting on the set of their film The Oranges.

Let’s hope the new baby’s arrival doesn’t steal too much thunder from Meester’s sweet longhaired dachshund Trudy, who’s made frequent appearances on the actress’ Instagram:
