Grammy winner Christina Aguilera performed the National Anthem at Sunday's Super Bowl XLV in Texas, flubbing the lyrics to Francis Scott Key's "The Star-Spangled Banner."
Singing the tune live, Aguilera, 30, was four lines into her rendition when she sang the words "what so proudly we watched" instead of the correct lyrics, "o'er the ramparts we watched." (Watch a clip above)
"I have been performing the anthem since I was seven years old and I must say the Super Bowl is a dream come true," Aguilera has said of earning the honor to perform during Sunday's showdown against the Green Bay Packers and Pittsburgh Steelers. "I am really excited to be part of such an iconic event."
The Black Eyed Peas are set to offer halftime entertainment at the NFL event, held at Cowboys Stadium in Arlington, Texas.
