Selena Gomez performed at the Dallas Cowboys-Oakland Raiders halftime show on Thanksgiving at AT&T Stadium, and the starlet looked smokin' hot as she took the stage to sing "Walk Like A Champion" and "Come & Get It." Take that, Justin Bieber!

After it was announced that the 21-year-old singer would be performing at the game, she told reporters, "I'm from Texas, so I'm a little nervous, I'm not going to lie. But I'm very honored and I hope that we come -- me, my dancers and my band -- and we give Texas a really good show and I make them proud."

The kicked off the Salvation Army's 123rd annual Red Kettle Campaign, a holiday drive that provides toys, food and shelter for families in need, and Gomez tweeted, "Proud to be performing for a great organization today during the @DallasCowboys game. Support @SalvationArmyUS."
