Leighton Meester, Adam Brody Leighton Meester, Adam Brody

Leighton Meester and Adam Brody are proud new parents, Us Weekly reports.

The Gossip Girl and O.C. alums, who were married in 2014, welcomed a baby girl on Aug. 4 and named her Arlo Day, according to TMZ. (Initial reports said Meester gave birth last week.) Much like their wedding, which also was kept under wraps until after the fact, the couple did not publicly announce ahead of time that they were expecting.

Brody, 34, and Meester, 27, have co-starred in The Oranges (2011) and Life Partners (2014). Brody is also currently starring on DirecTV's Billy & Billie. This is the first child for both.
