Blair Waldorf and Seth Cohen are having a baby! Well … sort of.

Actors Leighton Meester, 29, and Adam Brody, 35, have just confirmed they are expecting their first child together, Us Weekly reports.

The Gossip Girl star had been spotted out and about in Los Angeles with what looked like a growing belly -- so it appear as though she could not hide the good news any longer!

The under-the-radar couple secretly wed back in February 2014, after quietly dating for a few years. The brunettes first met on the set of the dramedy The Oranges in 2011.

While they were a couple, the duo filmed the movie Life Partners in 2014.

Congrats to the growing family!
