John Mayer's Famous Girlfriends
The pair dated from 2006 to 2007, but it wasn't until a 2010 Playboy interview that Mayer spoke publicly about his attraction to the "I Wanna Love You Forever" singer. "That girl is like crack cocaine to me," he said of Simpson. "Sexually it was crazy. That's all I'll say. It was like napalm -- sexual napalm."
