Mayer: 'Jessica Simpson is a good soul'

Singer John Mayer has defended his ex-girlfriend Jessica Simpson after Dallas Cowboys fans branded her a bad luck charm.

Simpson is dating American football star Tony Romo and Cowboys fans have blamed her for his poor performance against the New York Giants.

However, in his official blog Mayer has criticised the Cowboys fans, insisting that nobody is more passionate about their home state than Simpson.

"I have never known anyone to have more pride in their home state and their upbringing in it than Jessica Simpson has in Texas," he said.

"All witty barbs, blogs, and fashion policing aside, that girl loves Texas more than you know. It's one of her most defining traits as a person. So please don't try and take that away from her.

"I just thought it would mean something coming from the guy who has the absolute least to gain from this. And if I'm out of line in having written it, too bad. I can spare a Wednesday's worth of bad press if it means sticking up for a good soul."
