Well that didn't last long. It seems as if the giant headed singer John Mayer is already cheating on poor pitiful Jen Maniston! Page Six reports that a source in New York saw Mayer, a notorious horndog, out at 1Oak Friday night (the same place Lindsay stole the fur from)with Adam Levine, and Mayer “was all over some blond girl.” Mayer later asked the DJ to play some R. Kelly songs so “we can dance with our girls.”
