American musician John Mayer claims that he has been well-behaved with all his girlfriends contrary to his bad boy image.

'I consider myself a good guy, with the best of intentions. Anyone who has been in a relationship with me would stand by the fact that I've never been callous. I've never been a bad boy. I may have taken someone through the wringer psychologically, but I've never been sinister,' contactmusic.com quoted Mayer as saying.

Mayer has dated a string of women, including Jennifer Aniston, Jessica Simpson and Jennifer Love Hewitt.
