Report: Jennifer Aniston and Gerard Butler More Than Just Co-Stars

Jennifer Aniston is never alone for long.

The former "Friends" star has gone from Brad Pitt to Vince Vaughn to some male model who looks like Brad Pitt to John Mayer to Bradley Cooper and now....

To Gerard Butler!

At least that is what Star magazine is reporting on the cover of their latest issue.

“Let me put it this way,” a source on the New York set of their movie, "The Bounty," told Star. “They’re both hot and single! After they finish a scene, they stick around so they can hang out with each other. Neither is in a rush to leave."

The source says the pair is putting in some extra kissing scene practice as well.

“She says Gerard’s a great kisser,” the source revealed.

Apparently the feeling is mutual. The magazine cites another insider as saying “Gerard’s been after Jen ever since they met at the Toronto International Film Festival in September. She said no to him for almost a year, but he never gave up."
