George Clooney and Sarah Larson 03.08George Clooney and Sarah LarsonAll is not well in the Clooney homestead.

They've had an unwelcome caller...

Who had a message for Georgie boy about his lady, Sarah Larson.

The caller is reported to have told the George: “Dude, your friends asked me to give you a message, 'Dump the b**** before you're sorry.'” Chilling - non?

But is this the kind of thing was was meant to be a bit of a laugh?

Well, George doesn't think so... he's convinced that his friends weren’t involved.

He told the New Yorker: “It's not a prank - none of my friends would do that."

George told the paper that he definitely didn't appreciated the warning, and enlisted the help of his chauffeur (random) who traced the call to a pre-paid mobile phone.

But unfortunately, they haven't found the culprit.

What a bizarre tale indeed.
