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 favour with the public and now he's given up that quest, he is a changed man.
In an upcoming interview with U.S. news show Sunday Morning, he says, "It's very liberating when you finally realise 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).
