Congratulations! Leighton Meester and Adam Brody have welcomed their second baby

And baby makes four!

It seems congratulations are in order for Leighton Meester and Adam Brody —as the couple welcomed their second child earlier this week.

The notoriously media-shy couple didn't announce the birth via their social channels or, indeed, anywhere, but it was actually Brody who let the cat out of the bag in a rather casual manner.

Meester's husband of six years joined Hold the Phone TV's The Fun Time Boys Game Night Spectacular earlier this week, alongside eight other contestants, to play trivia games. And according to the Daily Mail, at some point during the game, the 40-year-old confirmed that he and Meester recently welcomed their second child—a boy.

Someone mentioned that Brody has a new child, to which he responded, "I have a new...yeah, since last I played I have a new kid." He confirmed that his new baby is "a boy and he's a dream, he's a dream boy."

Meester, on the other hand, has not yet spoken publicly about her the arrival of her second baby, and instead kept her social media focused on promoting a t-shirt as part of her partnership with Feeding America – and charity that helps feed the hungry in the US.

The rumours about the Hollywood couple expecting another baby started back in spring, when Meester was spotted strolling around LA, dressed in a grey t-shirt and black overalls with her growing baby bump on full display.

Brody and Meester began dating in 2013 and got married a year later in February 2014. The couple welcomed daughter Arlo Day who in 2015.
