John Mayer: 'I'm not the jerk I was before'

Rocker John Mayer insists he is no longer the "jerk" he once was when he spilled all about his romances with Jessica Simpson and Jennifer Aniston back in 2010.

The Your Body Is a Wonderland hitmaker revealed intimate details about his relationships with his famous ex-girlfriends during a candid Playboy magazine interview, famously describing Simpson as "sexual napalm", and he earned himself a reputation as a womaniser after dating and dumping stars like Jennifer Love Hewitt, Minka Kelly and Taylor Swift, who is said to have used Mayer as inspiration for her cutting break-up track Dear John.

However, Mayer - who is now dating Katy Perry - claims he was only trying to gain favor with the public and now he's given up that quest, he is a changed man.

In an upcoming interview with news show Sunday Morning, he says, "It's very liberating when you finally realize it's impossible to make everyone like you. I wanted everybody to like me. I thought I was one shuck and jive away in every direction."

The full chat is due to air this weekend (10Feb13).
