Mariah Carey thinks Eminem is obsessed with her - and maintains in the March issue of Playboy that she never had an affair with the rapper. "Something is clearly askew with him," Carey told the mag, "and I'm not quite sure what it is." Carey first denied the relationship last year, and Eminem spoke back by calling the diva a liar on the air. "I just heard something else he recently said about me," Carey continued. "I'm curious as to why he's so obsessed with me. I never got an apology letter, by the way... Then again, I wasn't exactly searching my mailbox for it."source
