Seth Cohen and Blair Waldorf are officially parents!

Us Weekly reports that Adam Brody and Leighton Meester have welcomed their first child, though they have not publicly acknowledged the birth, which reportedly took place sometime within the past few weeks. The couple, who have kept a low profile since marrying in a secret ceremony in February 2014, never publicly addressed Meester's pregnancy, and did not reveal their new child's gender or name.

This is the first child for both Brody and Meester, though their television peers have been busy with the babymaking business recently, too. Brody's "The O.C." costar (and ex-girlfriend) Gossip Girl" castmate Blake Lively gave birth to daughter James with Ryan Reynolds in January. We'd love to see that playgroup get together some day.

And there may be many more siblings on the way for Baby Brody in the future. Brody joked in a Reddit AMA back in August 2014 that he and Meester were looking to expand their brood considerably.

"I say twelve," he responded when asked how many kids he and Meester plan on having. "And I decide!"

Congrats to the happy family!
