Perez Hilton Insists John Mayer is Bisexual, Takes Lie Detector Test to Prove It.

Now that word is out about their steamy make-out session, Perez Hilton is hell-bent on proving that singer John Mayer swings in both directions. "He is definitely bi," Perez declared on Ryan Seacrest's KIIS-FM radio show, adding that John is "struggling with his sexuality."

Perez also reveals more details about their alleged infamous night at New York hot spot Stereo: "He kissed me, and I kissed him back. It was on the mouth with tongue. I thought he was messing with me," he says. "Then he kept going and going."

According to Perez, this salacious interaction occured last year, when Mayer was still with Jessica Simpson—and, Perez says, Jessica didn't mind one bit! "While John Mayer and I are making out, she is rubbing his crotch," he claims.

John's rep is rubbishing the reports: "This is all so ridiculous." To which Perez retorts, "It's 100% true." The pseudo-celeb blogger even went so far as to take a lie detector test for Us Weekly to prove that he speaks nothing but the truth. He passed.

Um, true or not, this is behavior is way stalkerish on Perez's part. Clearly that night meant more to you than it did to him, Perez. Give it up already! We can only hope that this is all part of some elaborate April Fool's joke—or has something to do with Ashton Kutcher's fake-out show Pop Fiction.
