Leighton Meester and husband, Adam Brody are the newest parents in Hollywood.
News of the couple welcoming their first child together just broke on September 24 even though there are reports their daughter arrived over a month ago.
The former 'Gossip Girl' star gave birth to her child on August 4 in Whittier, California, TMZ claims.
The site adds that the couple is "pretty private", so it comes as no surprise that she kept the news under wraps for over a month.
According to a close source, the couple have named their baby girl, Arlo Day Brody.
Meester and Brody tied the knot in early 2014 just a few months after news broke that they were already engaged. They however began dating in 2012 although there were rumors that they first hooked up on set of 'The Oranges' back in 2011.
