IRVING, Texas  —  Boo-hoo, Big Blue. Jessica Simpson won't be there.

The beautiful bad-luck charm and gal pal of Dallas quarterback Tony Romo will not attend Sunday's Giants-Cowboys playoff clash, her rep said.

This is a huge blow to superstitious Giants fans who wanted Simpson there to jinx her golden boy.

"She is not attending. She's working on a new album," said Cindy Berger, publicist for the dishy distraction. "She will not be there, but she'll be watching [on TV] and cheering [Romo] on."

Romo played his worst game this season when Simpson was in the stands for a loss to the Eagles.

"Ouch," said Giants fan Zach Curran, 26, of Jersey City at the ESPN Zone Tuesday, upon hearing that Simpson would be a no-show. "The Giants needed her like a 12th man or a secret weapon."
