Romo Sings Along to Jessica's Tunes

As though it weren't bad enough their team got throttled yesterday and their QB is out, now Dallas Cowboys fans wake up to this news: Tony Romo actually listens to Jessica Simpson's songs ... and knows all the words.

So says People, which reports the Cowboy was spotted at Jessica's Dallas show the other day -- and says he was "caught singing along to a few songs." And it gets even better: Whether intentional or not, People hilariously notes, "When Simpson hit a powerful note ... he clapped in awe." Our italics.
