Rachel Bilson and Adam Brody Break Up

Another blow to the OC came today (if you consider the loss of Mischa Barton a blow), when sources confirmed to US Weekly that OC stars Rachel Bilson and Adam Brody are dunzo.

The first clue was at the November 29 Volkswagon Concept Tiguan event in Hollywood, when Adam was putting the moves on Ashlee Simpson. Rachel was nowhere to be found at the time. US Weekly has learned that the split actually happened two weeks before that, after a month spent trying to work things out.

So what happens on the OC now?
