After he expounded on love and second chances during an August 22 concert at the Hollywood Bowl, people were sure John Mayer was talking about Jennifer Aniston, with whom he’s had an on-again, off-again relationship. "I believe in second chances ... Who else believes that when they fall in love again, this time it will be forever? That the next time with that person, you are going to do it better," Star reports Mayer saying. But days later at a concert in Irvine, California, Mayer announced, “I’m completely single!” He proceeded to fill the crowd in on the details of his singledom, saying that he has a morning ritual of Internet porn and is especially obsessed with a particular brunette on RedTube. “That’s the dirty truth,” he concluded.
