Pop star Jessica Simpson has failed to impress her new boyfriend Tony Romo's American football teammates - and has been banned from attending their games. Simpson made her romance with Romo public after showing up at the Dallas Cowboys' Sunday (16Dec07) game wearing a miniature version of his jersey. But members of the Dallas Cowboys have blamed Simpson's appearance for Romo's lacklustre performance - and are urging her to watch the games from home - after Romo's relationship with singer Carrie Underwood earlier this year (07) was criticised for adversely affecting Player Terrell Owens says, "Right now, Jessica Simpson is not a fan favourite in this locker room or in Texas Stadium. I think with everything that has happened, and obviously the way Tony played and the comparison between her and Carrie Underwood, I think a lot of people feel like she's probably taking his focus away. "I've got a message for her when we make the playoffs. Just stay tuned."
