John Mayer headed home after joining Jeff Beck onstage last night in LA. He tweeted about having been nervous for the performance, but he apparently has a new lady friend to help calm him down. John's rumored to be seeing 23-year-old aspiring actress Scheana Marie Jancan after they met during a recent evening out on the town. Whether or not their romance proves to be the real deal, it sounds like things with him and Jen are finally over for good.
