Heather Mills takes a tumble on stage

Heather Mills took a tumble while performing a dance routine on US TV show Dancing With The Stars.

Mills, who has a prosthetic leg, was performing a samba with her partner Jonathan Roberts when she slid and fell.

Despite the fall, however, the pair received a score of 21 out of 30 and Mills was praised by the judges for her bravery in the face of a disability.

Judge Carrie Ann Inaba said: "The fact that you fell just reminds me of how amazing it is that you're in this competition, because you run that risk every time you get on the floor."

Mills, who is currently going through a lengthy divorce settlement with Sir Paul McCartney, has spoken openly about the challenges she faces with a prosthetic leg.

She told the Daily Mail: "I'm quite happy to be thrown around, and hopefully my leg will stay on. It's very unlikely my leg is going to fly off, although it would be quite funny."
