'I Was Just A Jerk' - John Mayer Comes Clean

John Mayer has a simple explanation for why he has so many exes: 'I was just a jerk.'

Mayer sat down with CBS Sunday Morning, and talked about why he's made so many headlines with public comments about his exes.

That's a far cry from comments he's made about exes like Jessica Simpson, Jennifer Aniston, and Taylor Swift in the past. Mayer likened Simpson to "sexual napalm," and chided Swift for her song "Dear John," although Swift claims the song isn't about Mayer.

Still, saying 'I was just a jerk' and copping to some missteps is a big step for Mayer, who is currently dating fellow singer Katy Perry. To catch the full interview, check out CBS Sunday Morning this weekend before the Grammy Awards!
