John Mayer just got more candid than ever, opening up about Jessica Simpson, Jennifer Aniston and his "white supremacist" private parts. Yes, white supremacist.

In an interview with Playboy, Mayer explained that he was practically addicted to ex-girlfriend Simpson. "That girl, for me, is a drug," he said. "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."

Mayer was a little tamer in their discussion on his other highly publicized relationship with Jennifer Aniston, and cited something unusual as a reason for their breakup. "One of the most significant differences between us was that I was tweeting," he said.
