Christina Aguilera made an astonishing gaffe by botching the lyrics to the American National Anthem as she kicked off the Super Bowl on Sunday night.
The 30-year-old singer performed a throaty rendition of The Star-Spangled Banner to open the NFL championship - but sang incorrect lyrics that matched an error from Wikipedia.
What she should have sung in the middle of the song was: 'Whose broad stripes and bright stars, through the perilous fight, O'er the ramparts we watched, were so gallantly streaming.'
Whoops! Christina previously performed during the half-time show at the 2000 Super BowlBut what she sang instead, as over 100 million people watched, was 'Whose broad stripes and bright stars through the perilous fight, What so proudly we watched at the twilight's last gleaming.'
That error matches one that used to exist on the Wikipedia entry for the Star Spangled Banner Lyrics.
Wikipedia is a user-generated online encyclopaedia that depends on the community for accuracy.
A change made to the Wikipedia entry for The Star Spangled Banner may explain why Christina Aguilera flubbed the lyrics. The mistake on the website, as seen hours before the Super Bowl and since fixed by a user, matches the mistake she sang 
Apology: The singer later said: 'I got so lost in the moment of the song that I lost my place'The star later apologised for her slip-up, telling CNN: 'I got so lost in the moment of the song that I lost my place.'
She continued: 'I can only hope that everyone could feel my love for this country & the true spirit of it's anthem still came through.'
Viewers at home were quick to take to Twitter to point out Aguilera's slip-up.
'Christina Aguilera just killed the National Anthem bet by singing the wrong words,' tweeted @darrenrovell within seconds of the mistake.

'I covered a war, I covered the stuff in Haiti last year. You always figure if something is going to happen it would be in one of those places - not at a football game.'
