For once in his life, John Mayer is not talking about a past relationship. John is on Ellen today and Ellen asked John all about his relationship with Katy Perry. He told Ellen, “It was a very private relationship going in, it was private relationship during, and it’s a very private relationship still. I can understand asking the question based on some previous answers I’ve given, but I finally learned how to put the wall between one thing and another. Coupling is a tricky thing.”
I have to say I can't believe John stayed quiet. I'm guessing he either is holding out hope for another chance with Katy or she caught him in a position that he would rather not have her reveal so is staying quiet.
