Rachel and Adam: dunzo

O.C. cuties Adam Brody and Rachel Bilson have definitely ended their two-year relationship, according to Life + Style mag. There has been speculation for a few months about the demise of the off-screen couple, and a friend close to them confirmed, "They've been done for a few weeks. They are just done. That's all there is to it. There's no drama. They just ended it." Brody turned up alone to the launch of the Volkswagon concept car last week, and "was definitely acting like a single guy," according to a witness. Reps for the pair have not commented.
