Heather Mills is said to be struggling with her training regime for Dancing On Ice 2010.

Heather took part in America’s Dancing With The Stars in 2007 and thought that ITV’s ice dancing show would be a similar experience. However Heather, who wears a prosthetic leg, is said to be suffering from extreme pain in her stump after a few skating rehearsals.

A source told The Sun: “Ice skating is much more demanding.

“Heather is suffering a lot of pain.”
