John Mayer said he's "quite happy" in his relationship with Katy Perry, and things seem to be going fine with the couple.

But it wasn't that long ago when Mayer was considered by some to be the worst sort of womanizer, and in an interview which will air on CBS's "Sunday Morning," he's owning up to it.

"I was just a jerk," Mayer told CBS' Anthony Mason on the show, speaking about his past behavior. After all, who could forget his 2010 Playboy interview, where he referred to his ex-girlfriend Jessica Simpson as "sexual napalm," dished on his relationship with Jennifer Aniston and made seemingly racist comments about the types of women he prefers?

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.

Mayer said that dealing with losing his voice for months following vocal cord issues and surgery wasn't as difficult as dealing with the bad PR he got from all his "open mouth, insert foot" comments.
