John Mayer confirms split from Katy Perry on Ellen Degeneres Show

He's been part of quite a few celebrity couples. John Mayer has dated Jennifer Aniston, Jessica Simpson and, most recently, Katy Perry. The singer stopped by to chat with Ellen DeGeneres for a segment on her Tuesday show and talked about his love life, his life in Montana and his love of scotch.

Ellen mentioned that the last time she saw Mayer was at the Grammys and he was sitting with Katy Perry.

"Correct," he replies.

Ellen gently tries to ask what happened by saying, "I love you and my thoughts are with you. It's nobody's business but"

Mayer replies, "Thank you. Listen, it was a very private relationship going in. 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. I've been much happier since then. I'm on the same journey as everyone else. Coupling is a tricky thing."

As for his health, Ellen asked if his throat problems were due to acid reflux.

"Yeah, that's half of it," says Mayer. "Half of it is over use and singing and singing and singing."

He went on to say, "The other stuff is you know, what you put into your body. And, I'm getting to that age now your body doesn't just shake everything off and it didn't help that I really loved, love, loved scotch. It's just like applying poison to your body. It's like applying a shellac of poison. It's just delicious, wonderful poison. That makes you not care how late you're out till or where you're going but I had to really say I like singing and writing more than I like delicious scotch so I had to really dial it down. And, I'm a little more boring now."
