Leighton Meester, Adam Brody Reportedly Dating

"The O.C." and "Gossip Girl" never crossed airwaves, but it looks like Seth Cohen and Blair Waldorf will remedy that oversight on their own.

According to Us Weekly, actors Adam Brody, 33, and Leighton Meester, 26, have been secretly dating for weeks! The two starred together in last year's dramedy "The Oranges," in which Leighton played the much younger love interest to Adam's on-screen dad Hugh Laurie.

Now, we've seen our fair share of teen show stars date within their cast. You'll recall Blake Lively and Penn Badgley's three-year romance, and "Vampire Diaries" co-stars Nina Dobrev and Ian Somerhalder can't seem to get enough of each other. But we have a tough time recalling another cross-over romance quite like this one. I guess Chrismukkah came early for us couples watchers!

What do you think of Adam and Leighton dating? Do they make a good couple? Sound off in the comments and on Twitter!
