John Mayer finally has revealed why it did work out with Katy Perry on Tuesday’s episode of Ellen. It isn’t that easy! “It was a very private relationship going in,” he explained. “It was a private relationship during and it’s a private relationship, still. I can understand asking the question based on some previous answers I have given but I have finally learned how to put the wall between one thing and the other.” He also added, “I’ve been much happier since then. I’m on the same journey as everyone else. Coupling is a tricky thing.” Ouch. See exactly what he said below.
