John Mayer is mad at Taylor Swift John Mayer and Taylor Swift Thu-07-Jun-12 08:16 Share this By Jay-Jay FeeneyJOHN MAYER is upset and humiliated by the song TAYLOR SWIFT supposedly wrote about their relationship, “Dear John”.They dated for a short time in 2009 although they’ve never admitted it out loud.After they split, Taylor released the song “Dear John” with some harsh lyrics.John says, "It made me feel terrible. Because I didn't deserve it. It was a really lousy thing for her to do.""I will say as a songwriter that I think it's kind of cheap songwriting. I know she's the biggest thing in the world, and I'm not trying to sink anybody's ship, but I think it's abusing your talent to rub your hands together and go, 'Wait till he gets a load of this!' That's bulls**t."But let’s not forget that John Mayer has openly talked about his former relationships. He told everyone why he broke up with Jennifer Aniston in 2010:"There was a rumor that I had been dumped because I was tweeting too much. That wasn't it, but that was a big difference. The brunt of her success came before TMZ and Twitter. I think she's still hoping it goes back to 1998. She saw my involvement in technology as courting distraction. And I always said, 'These are the new rules.'..."And Jessica Simpson:"That girl, for me, is a drug. And drugs aren't good for you if you do lots of them. Yeah, that girl is like crack cocaine to me... Sexually it was crazy. That's all I'll say. It was like napalm, sexual napalm..."And his song "Your Body is a Wonderland" is supposedly about Jennifer Love Hewitt.
