John Mayer: 'I was just a jerk' in past relationships

John Mayer -- with new love Katy Perry -- says he "was just a jerk" in his past relationships.

We're guessing John Mayer's' kiss-and-tell days are over. In a forthcoming interview with "CBS Sunday Morning," the "Clarity" singer and Katy Perry's new beau reflects harshly on his well-earned rep as a Hollywood heartbreaker who notoriously spills to the press about his breakups. 

"I was just a jerk," the 35-year-old Mayer tells host Anthony Mason. 

The blues rocker notes that he's changed since the days of his past interviews -- like that infamous 2010 Playboy sit-down when he compared former ladylove Jessica Simpson to "sexual napalm" and offered up TMI comments about ex Jennifer Aniston.

"It's very liberating when you finally realize it's impossible to make everyone like you," Mayer said, adding, "I wanted everybody to like me. I thought I was one shuck and jive away in every direction." 

The Grammy winner, who was forced off the road last year for 10 months so he could recover from vocal cord surgery, confessed that getting over the negative reaction resulting from his media interviews was a lot harder than dealing with the reoccurring granuloma that nearly robbed him of his voice.

Before hooking up with the "Firework" crooner, Mayer was also linked in the past to the likes of Jennifer Love Hewitt, Minka Kelly and Taylor Swift, the last of whom gave the singer-songwriter a taste of his own medicine by seemingly writing about their relationship in her hit "Dear John." 

The full interview with Mayer airs Feb. 10 on CBS "Sunday Morning" at 9 a.m.
