Adam Brody and Ben McKenzie, a.k.a Seth Cohen and Ryan Atwood from The O.C, both have baby news to share.
Brody's wife Leighton Meester has given birth to a baby girl.
The couple, who secretly wed in February 2014, reportedly welcomed their first child together on 4 August but have so far kept their baby out of the public eye.
TMZ reportedly obtained the birth certificate and claim the couple have named their daughter Arlo-Day.
The Gossip Girl star and friend of co-star Blake Lively who gave birth in January, recently told Nylon magazine she was excited about starting a family.
She added: "I like the grown-up stuff. I like having a house. I've got dogs."
Brody's co-star, Ben McKenzie, is reportedly also set to become a dad for the first time, as according to US Weekly McKenzie's girlfriend and Gotham co-star, Morena Baccarin, is pregnant.
McKenzie is best known for playing Ryan Atwood in The O.C and starring in Homeland.
This will be McKenzie's first child, and Baccarin's second. She also has a 23-month-old son Julius with her ex-husband Austin Chick.
