Christina Aguilera Falls Onstage At Grammys (VIDEO)

It hasn't been a good week for Christina Aguilera.

The singer, who famously flubbed the lyrics to the National Anthem at last week's Super Bowl, performed in a tribute to R&B legend Aretha Franklin with four other singers on Sunday. She executed the song "Ain't No Way" without any hiccups, but when she was leaving the stage, she fell down -- literally.

It's shot from afar and a bit blurry, but it's there, very obviously. Squint and then squirm. At least her performance was impressive.
