John Mayer may be a changed man and it’s all because of his releationship with pop singer, Katy Perry. The two have been dating for several months and John admitted in a recent interview that he’s “quite happy.”

But a little over a year ago many people might consider that he was a womanizer. In an interview with CBS “Sunday Morning” that was air this Sunday, John says “I was just a jerk!”

Attempting to explain his behavior, Mayer said, “I wanted everybody to like me. I thought I was one shuck and jive away in every direction.”

But now, he says, he’s changed. “It’s very liberating when you finally realize it’s impossible to make everyone like you,” he said.

Well, at least one lady does, Katy Perry.
