"Yeah, that girl is like crack cocaine to me. Sexually it was crazy. That's all I'll say," the singer told Rolling Stone about his relationship with Jessica Simpson. "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 my s--t just to keep f--cking you.'"
