As Christina Aguilera’s somewhat flubbed rendition of the National Anthem at this year’s Super Bowl proved, even a top-notch talent such as herself is capable of moments of imperfection. And now we have further, reassuring proof of C-Ags’ fallibility, with the blooper reel from her song-and-dance extravaganza Burlesque.

Hit up the video (warning: Some NSFW language) after the jump to see Aguilera, Cher, Twilight hunk Cam Gigandet and the rest of the Burlesque crew work through the kinks in their performances.
