John Mayer - Mayer: 'Sex With Simpson Was Crazy'

Rocker JOHN MAYER has risked the wrath of ex-girlfriend JESSICA SIMPSON by opening up about their sex life - admitting the singer/actress was "crazy" in bed.

Mayer confesses he fell for Simpson almost as soon as he met her in 2006, but their romance failed because she was like "a drug" for him.

He tells Playboy magazine, "(Simpson was like) a drug. And drugs aren't good for you if you do lots of them. Yeah, that girl is like crack cocaine to me.

"Sexually, it was crazy. That's all I'll say. It was like napalm, sexual napalm. Did you ever say, 'I want to quit my life and just f**kin' snort you? If you charged me $10,000 to f**k you, I would start selling all my s**t just to keep f**king you.'"

The couple split in 2007 after nine months together and Mayer went on to enjoy a relationship with Jennifer Aniston.
