They didn’t have the most high-profile relationship out there, but Bradley Cooper and Renée Zellweger have broken up after a two-year relationship that seemed pretty stable right up until the end.  Both seem to have handled the split well, though Renée has recently visited Sandra Bullock in New York for some much-needed girl talk and advice.
Perhaps Sandra Bullock isn’t the best person to talk to about relationship issues, but since she did just have a big breakup herself, she probably had a few good things to say to Renée.  Neither Bradley nor Renée have been linked to anyone new, and for now it looks like both these celebs are happy to stay single.
