Christina Aguilera Sings National Anthem At Super Bowl

Pittsburgh native's performance followed 'Glee' star Lea Michele's rendition of 'America the Beautiful.'

As football fans gathered on Sunday night (February 6) to watch the match-up between the Pittsburgh Steelers and Green Bay Packers at Super Bowl XLV, Christina Aguilera took to the stage to perform the national anthem. Moments earlier, "Glee" star Lea Michele performed "America the Beautiful" before kickoff in chilly Dallas.

Wearing her hair down and donning a black suit, Aguilera belted out the song as both the Terrible Towels and Cheese Heads counted down the moments until the big game. The Grammy winner got the crowd hyped as she hit the crescendos of the song, while celebrities and players looked on, many of the players nervously looking to the sky or holding back tears as they prepared to take the field.

Although her voice never wavered as she paid tribute to the country in song, Aguilera did briefly flub the lyrics, but she handled it like a pro, rendering the mistake barely noticeable.

The singer grew up outside of Pittsburgh and is presumably a Steelers fan.

"I have been performing the anthem since I was 7 years old and I must say the Super Bowl is a dream come true," Aguilera said recently. "I am really excited to be part of such an iconic event."
