Hangover star Bradley Cooper sure does get around quickly with hollywood starlets.

Dinner dates must be his specialty considering he took Jennifer Aniston out just a few weeks ago and most recently moved in on his Case 29 co-star Renee Zellweger!

Despite recent rumors, Cooper claims that he and Aniston are just “friends.” Figures he says this just days before hitting up his next flavor of the week.

Cooper and Zellweger were seen dining together in a quiet corner at Italian restaurant Antonucci on NYC’s Upper East Side on Tuesday night, according to Usmagazine.com.

“She was grinning ear-to-ear and laughing really loud,” a witness said. “Bradley kept moving closer to her and slouching in his seat. He was really relaxed.”

Who knows if these two are an item — but it’s no lie that they were enjoying each other’s company.

“He seemed to be hanging on to Renee’s every word,” added the onlooker. “They were lost in their own little world.”
