Jessica Simpson JSIMPSONJMAYER041307_06.jpg John Mayer and Jessica Simpson may not be an item any more - but that's not keeping John from sticking up for Jess in her hour of need!

In his most recent blog posting, Mayer speaks out on Dallas Cowboys fans' treatment of his former flame, particularly their accusations about Jess' alleged negative influence on QB Tony Romo.

"That girl loves Texas more than you know," Mayer says. "It's one of her most defining traits as a person. So please don't try and take that away from her."

"I have never known anyone to have more pride in their home state and their upbringing in it than Jessica Simpson has in Texas. I don't really follow sports, but I have played some of my biggest and best concerts in your state, and having witnessed how dynamic the spirit there is, I'm betting emotions are running high right about now."

Mayer was explicit about his intentions in writing the post, claimin "I just thought it would mean something coming from the guy who has the absolute least to gain from this."

"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."

What a kind gesture on John's part! We're guessing he just made a lifetime fan out of Tony Romo, too!
