George Clooney has ordered an investigation into a mystery caller urging him to "dump the b***h" referring to his girlfriend Sarah Larson.

Page Six reports that the "Leatherheads" actor had gotten a message left on his voicemail from a middle-age man who told him, "Dude, your friends asked me to give you a message: Dump the b***h before you're sorry!"

Larson, a former cocktail waitress, was outraged. She reportedly claimed, "'Before you're sorry.' They say that I'm a stripper. There's a ton of stuff about that. I've never been a stripper."

"You know, just because I'm from Las Vegas, I must be a stripper. Because I'm a cocktail server, that means I'm an escort."

The actor was certain the message wasn't from any of his friends. He said, "It's not a prank - none of my friends would do that."

However, the investigation came to an abrupt stop when the number was traced to a prepaid cell phone.

Clooney and Larson have been dating since mid-2007.
