Bradley Cooper's Hot Date With Renee Zellweger?

Bradley Cooper had a hot date Tuesday night NOT with Jennifer Aniston but with Renee Zellweger? The pair, who co-star together in the upcoming "Case 39," were spotted at Antonucci, an elegant Italian restaurant on NYC's Upper East Side.

"He pulled her chair out for her when she sat down and he kissed her on the hand," says the witness. "If they're just friends, they were being awfully affectionate!" Renee and Bradley were seated at a corner table, where diners describe their behavior as "flirty," "relaxed" and "cute together."
