Oops! I've fallen over again
Britney Spears has fallen on stage in Las Vegas and injured her ankle forcing her to reschedule two shows.
Video shot by an audience member shows Spears kicking and high-stepping on high-heels during her single (You Drive Me) Crazy before her left ankle gives way.
She went on Twitter to thank her fans for their well wishes, saying she "had a little scare on stage tonight with my ankle but I'm ok!".
The star's doctor recommended two days off.
