Bradley Cooper has a new enemy: Brad Pitt's ex-wife.

Jennifer Aniston "honestly feels screwed over" after her date with the "Hangover" star didn't lead to a second, reports US Weekly.

"She wanted to turn her date with Cooper into something," a source told the magazine of duo's dinner date in New York on June 18.

A few weeks later, Cooper was out with Renee Zellweger, but apparently Aniston "doesn't see what Renee has that she doesn't," the insider tells US.

Perhaps it is what Zellweger doesn't have that Cooper likes says: ie, no drama.

"She just does her thing, has her friends and her life and is cool. She's really happy and doesn't need anyone to feel complete," the magazine quotes another insider as saying about Zellweger.

But Aniston's going to be alright, adds a pal. Why? "She's used to rejection."

Yikes! With friends like that...
