Rachel Bilson and Adam Brody, The OC’s onscreen and once-offscreen couple, have broken up after two years together. These two were said to be having problems a few weeks ago due to Rachel getting too close to her costar in “The Last Kiss,” Zach Braff. It looks like they parted at some point and were able to keep it a secret for quite a while. Rachel and Adam were seen out separately several times, and it’s not too surprising that they’re no longer together. They were an adorable couple though and this is sad news:

Onscreen lovebirds Rachel Bilson and Adam Brody, who play a cute couple on The O.C. and have also dated offscreen since 2004, have decided to call it quits.

“They’ve been done for a few weeks,” a friend close to the couple tells Life & Style. “They are just done. That’s all there is to it. There’s no drama. They just ended it.”

That may explain why Adam showed up solo to a party on Nov. 28 for the U.S. premiere of Volkswagen’s concept car Tiguan in LA.

“He was definitely acting like a single guy,” an eyewitness tells Life & Style.

According to nightlife insiders in LA, he’s been spending a lot of time without Rachel at the clubs with his guy friends.

Reps for the two would not comment.

I was kind of hoping these two were solid, but they were both just 26 and that seems kind of young to settle down in Hollywood.
