Aguilera may have had the biggest fumble of the night when she messed up some of the lyrics to "The Star-Spangled Banner." Watch:
Of course, she can take comfort in knowing that she isn't the first celebrity to struggle through the song. Surge Desk collects some other famous national-anthem screwups.
In 2001, the Aerosmith frontman played off his forgetfulness rather cleverly. After struggling to find the phrase "the home of the brave," he ad-libbed, "the home of the Indianapolis 500."
At a 2009 NASCAR race, McCartney, a singer/actor, got lost early in the song.
The R&B singer got confused somewhere along the way while singing the anthem at a 2010 Lakers-Hawks game.
Mike Eli of the Eli Young Band
The lead singer of this country band messed up the third line of the national anthem at a 2010 Chiefs game -- then he started over and flubbed it again. Ouch.
At a 1990 Padres game, the comedian butchered the anthem with her way-off-key warbling. At least she seemed to have the lyrics under control!
