Rachel Bilson confirms broken engagement to Hayden Christensen

hayden-christensen-rachel-bilson.jpgIt's terrible to admit, yes, but was this a celebrity couple that anyone was ever rooting for? Former "OC" star Rachel Bilson and Hayden Christensen (the "Stark Wars" franchise) have been engaged for two years -- and an item for three -- but no more.

Bilson's rep confirms the demise of their union, telling People, "Yes, the engagement is off." Further explanation is left to rumors, but fortunately there's a lot of those.
