The tempremental songbird says she thinks the rapper is disturbed, after she had to deny his allegations that the pair had been romantically involved.

She tells Playboy magazine, “I just heard something else he recently said about me. Something is clearly askew with him and I'm not quite sure what it is.

"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."
