Leighton Meester & Adam Brody Expecting Baby #2

“Gossip Girl” actress Leighton Meester, 33, and “O.C.” actor Adam Brody, 40, have another baby on the way!

Meester is pregnant with their second child. In photos obtained by DailyMail.com, the 33-year-old debuted her growing baby bump while taking a stroll with Brody in Los Angeles.

It is unknown how far along she is, but it won't come as a shock if Leighton gives birth sooner than later.

Nearly five years ago, Meester welcomed their daughter Arlo, just three months after news broke that she was expecting.

In September, Leighton gushed about motherhood, telling Us Weekly, “People started telling me before [I had] a kid, 'You're going to really love them. Then you're like, 'Yeah, obviously, I'll love them.' And then you do [have them] and you're like, 'Oh. Okay. I don't love anyone else. I just love them. And I don't even love myself as much as I love them! Not even close.' I don't know, would I kill somebody or die for them? Sure. I would.”

Leighton and Adam have been private about their relationship for years. Adam recently shared to GQ, “We're homebodies. We don't go to a lot of things that perhaps we could, and don't seek out promotion in that way. I'm not s--tting on anyone who monetizes that aspect of their life because I get it. But we've found this great balance so far that really works for us. We're also not very active on social media."

He added about his wife of five years, “She's more inherently private than I am.”

Leighton and Adam met on the set of their 2011 film “Oranges” and secretly tied the knot in 2014.

Adam's ex-girlfriend Rachel Bilson recently commented on their split nearly 14 years ago. After In Style posted a throwback photo of them, joking that their breakup “ruined high school for all of us,” she quipped, “IM SORRY!”
