"Britney injured her ankle during her performance Wednesday evening and her doctor has advised her not to perform Friday and Saturday evening so that she may heal," they said in a statement.

During her performance of "(You Drive Me) Crazy" (at the very end of the video), the 33-year-old pop princess toppled over in her sky-high heels and then sat there for a moment, clearly injured from the fall.
The embarrassing moment was caught on video by a few fans in the audience, and Spears even took to her Twitter to address the injury.
"Thank you for all of the sweet wishes!" she wrote on Thursday. "Had a little scare on stage tonight with my ankle but I'm ok!"

Will the show go on? Spears is a resident at Planet Hollywood for her Piece of Me show, and her next show is scheduled for May 1. The "Pretty Girls" singer has a two year deal with the venue that reportedly earns her $15 million per year ($310,000 per show).
