John Mayer has been dating plenty of Hollywood women the past few years, and ever since last summer he's been Katy Perry's boyfriend. The couple split back in March, and now he's spoken about it with Ellen DeGeneres.

"It was a very private relationship going in," he said to Ellen. Ellen, who's friends with Katy, responded: "I know Katy. She is a good friend, and I know that since then, you're not together anymore. And I just want to say, I love you and my thoughts are with you."

John later summed it all up by saying "I've been much happier since then."
