Well well well, it looks like Jessica Simpson was texting Mr. Horn Dog himself, John Mayer.  No wonder Tony Romo dumped her.

A snitch said, “They were hanging out and he picked up her phone and she got defensive about it. Tony found messages from John and went ballistic. Tony dumped her right then. He walked out and that was it.”

She was obviously bad luck anyway, but still she’s hot and he will be back!  He doesn’t want to fumble another big one away….
