"That girl, for me, is a drug," Mayer tells the March issue of Playboy in an excessively candid interview. "And drugs aren't good for you if you do lots of them. Yeah, that girl is like crack cocaine to me."

Mayer and Simpson dated on and off from 2006 to 2007. "Sexually it was crazy," he says. "That's all I'll say. It was like napalm, sexual napalm."

John was coy, however, when talking about ex Jennifer Aniston.

"I love Jen so much that I'm now thinking about how bad I would feel if she read this and was like, 'Why are you putting me in an article where you're talking about someone else? I don't want to be in your lineage of kiss-and-tells'."
