The Ex: Jessica Simpson
Talk about an explosive interview! Years after his on-off relationship with Simpson ended in 2007, Mayer told Playboy in February 2010, "Sexually it was crazy. That's all I'll say. It was like napalm, sexual napalm." Responding to his TMI tell-all, in which he also compared her to crack cocaine, Simpson got the last laugh: "He'll never have this napalm again," she joked on The View a month later.
