NEW YORK: Rocker John Mayer has denied reports suggesting he is dating aspiring actress Scheana Marie Jancan. The singer specified that he doesn’t have a girlfriend at the moment and is single, reported aceshowbiz.com “If I had a girlfriend, she would be incredibly offended by me saying, ‘I don’t have a girlfriend’,” he said. “If you were the woman and you stepped out and said, ‘I’m not with anybody, you’d have to go home and take a lashing for the next three weeks! So that’s the proof.”
