Adam Brody, best known for his role on The O.C., and wife Leighton Meester welcomed their first child–a baby girl–into their world back in early August. The Gossip Girl alum and her daughter are both thriving following the birth more than a month ago.

Going against the grain of celebrity traditions in L.A., Adam Brody and Leighton Meester didn’t have their baby at Cedars-Sinai Medical Center. TMZ just recently got access to the baby’s birth certificate, and announced that the couple has named their daughter Arlo Day Brody.

Adam Brody and Leighton Meester tied the knot back in February 2014, during a secret ceremony. Given their silence about their wedding, it’s not surprising they hid their baby’s birth from the media, too. In fact, Leighton Meester and Adam Brody chose a hospital that was around 30 miles away from Cedars-Sinai.

The new mom was last spotted back in July near Sherman Oaks, where she boasted a very large baby bump.

Prior to their daughter’s birth, Adam Brody joked about the number of children they planned in having.

“I say 12,” he said. “And I decide.”

Best wishes to Adam Brody and Leighton Meester on their first foray into parenthood–and those 2:00 a.m. feedings.
