Christina Aguilera Super Bowl National Anthem

Christina Aguilera is featured singing the National Anthem at Super Bowl XLV during the highly anticipated game.

Aguilera had a slight lyric malfunction substituting, "O'er the ramparts we watched were so gallantly streaming" with "What so proudly we watched at the twilight's last gleaming."

The five-time Grammy winner is known for hitting high ranges with sustainable octaves that most singers can only dream of mastering. The half-time show will feature the Black Eyed Peas. 

Each year just before the opening kickoff of the Super Bowl, a renowned performer sings the "Star Spangled Banner." Other stars to have sung the national anthem at the Super Bowl include Carrie Underwood, Billy Joel, Diana Ross, Neil Diamond, Mariah Carey and Beyonce Knowles.

The world broadcast on Feb. 6, 2011 is pitting the Green Bay Packers and Pittsburgh Steelers at the Cowboys Stadium in Arlington, Texas, with the Packers as the favorite for this round.

A dramatic shot that opens with a football player shedding a tear as Christina Aguilera belts out her rendition of the National Anthem.  The pop star added her signature vibrato and power singing to the tune, and finished the song with an official fighter-jet flyover.
