IT’S goodbye Jennifer Aniston, hello Renee Zellweger for Bradley Cooper. The star of “The Hangover” was spotted on a cozy date with the “Bridget Jones” cutie (left) at Antonucci on East 81st the other night. A witness told OK!: “He pulled her chair out for her when she sat down and he kissed her on the hand. If they’re just friends, they were being aw fully affectionate. Throughout the dinner they were playful and flirty. She played with her hair a lot, and she would often touch his arm when she was making a point about some thing.”
