Washington Wizards star guard John Wall was at the Redskins-Cowboys game on Sunday dressed in a Cowboys jersey of Emmitt Smith. He also said hello to Dez Bryant and threw up the X.

Wall, who despite being firmly entrenched in Redskins' territory is remaining true to his roots as he continues to cheer for the Cowboys.

Wall admitted as much when he was originally drafted by the Wizards but years later not much has changed. The All-Star point guard says, "I'm a mama's boy and that's my mama's team."

So what's up with all these Cowboys fans up in the East?

New Jersey Governor Chris Christie? Big Cowboys fan.

Cleveland Cavs superstar LeBron James? Big Cowboys fan.

And Cowboys fan Bryce Harper, the Nationals' stud outfielder, makes it at least three pro athletes from Washington (Dallas' long-time NFC East rival) that pull for America's Team.

Here's a list, including Harper, of the many celebs who pull for the Cowboys.
