I must admit, I didn’t even know the former Gossip Girl and O.C. man were dating!

This private couple have, apparently, been dating for less than a year and were first romantically linked in early February. At the time, a source told Us Weekly that the pair had been “secretly dating” after being friends for since working together on the 2011 film “The Oranges.”

Reps for Leighton and Adam have yet to officially confirm or comment on the engagement news, but a source gave the information to Wonderwall, who first broke the news.

No spotting of the ring yet, but I hope Brody did a good job!
