Terrell Owens has a message for Jessica Simpson: Stay away.

The 27-year-old singer-actress has become Public Enemy No. 1 among Dallas Cowboys fans because of a link being made between her appearance at Sunday's game and the poor performance of her new boyfriend, quarterback Tony Romo.

Asked Wednesday about the Simpson scenario, Owens playfully chimed in: "Right now, Jessica Simpson is not a fan favorite — in this locker room or in Texas Stadium."

The Cowboys lost 10-6 to the Philadelphia Eagles and Romo had what was statistically the worst game of his career, all while Simpson sat in a luxury box wearing a pink No. 9 jersey she proudly showed off for television cameras.

The problem for her is, Romo's previous worst game came last December at home to the Eagles when then-girlfriend Carrie Underwood was in attendance.

"With everything that has happened, obviously with the way Tony played and the comparison between her and Carrie Underwood, I think a lot of people feel she has taken his focus away," Owens said, echoing the chatter on sports-talk radio and blogs. "Other than that, she was high on my list until last week.

"Oh, I got a message for her when we make the playoffs. Just stay tuned."
