Troubled singer Amy Winehouse has launched a bizarre attack against music mogul Simon Cowell - blaming him for all the world's evils.

The Back to Black hitmaker mocked the American Idol judge's hairstyle, and criticised his treatment of contestants on U.K. TV talent show The X Factor.

She also blasted his fellow X Factor judge - Australian singer Dannii Minogue - for her behaviour on the show.

Winehouse says, "Let me say one thing that is pertinent and I won't swear on it either. It's got nothing to do with Simon Cowell, although everything that's wrong in the world probably does.

"I mean, he's the reason that all them hairdressers haven't taken their pictures out of the window since the sixties."

Referring to Minogue's performances on The X Factor, she added: "It's so embarrassing... Dannii always has to stand up. You ever noticed that?"
