First, the star was rumored to be dating Jessica Simpson.
Now, word is going around that Carrie Underwood is the player's new beauty of choice.
Underwood was a surprise guest at Texas Stadium for the Cowboys' Christmas Day game against Philadelphia, giving Romo a hug on the field before kickoff.
The Dallas QB also told a small-town paper in central Illinois, where he went to college, that he was dating the American Idol singer. The pair may have met at the Cowboys game on Thanksgiving Day, where Underwood performed at halftime.
Sadly, Romo's Cowboys played terribly against Philadelphia. But hopefully Carrie will bring her man more luck next time.
