Seems there are no hard feelings between Jessica Simpson and ex, Dallas Cowboys quarterback Tony Romo, who famously dumped her the day before her 29th birthday this past July.

"Can't forget the Cowboys! Great game yesterday," the singer, 29, posted on Twitter Monday.

Simpson also poked fun at being called a "Jessica Jinx" by Cowboys fans.

After the Cowboys beat the Philadelphia Eagles, 20-16, Sunday, she wrote: "My pink jersey was nowhere in sight ;) I was screaming in my parents' TV in Dallas gear though."

Moments later, she Twittered a personal shout-out to Romo (who wears a No. 9 jersey).

"'Tougher Than The Rest' YAY 9," she wrote, possibly alluding to the Bruce Springsteen song by the same title. (The song's lyrics include: "I been watching you awhile / maybe you been watching me too / so somebody ran out / left somebody's heart in a mess.")
