Heather Mills endures pain for TV show

Heather Mills has been training so intensely for US reality TV show Dancing with the Stars that she is suffering from blisters.

The estranged wife of Sir Paul McCartney wears a prosthetic limb after losing her left leg below the knee following a road accident in 1993, but she refuses to shy away from the show's gruelling training regime.

A source told Closer: "Heather has been through hell recently and it's great for her to focus on something other than her daughter and the divorce. But the show's rehearsals have left her in a lot of pain.

"The sores are especially bad where her leg joins her prosthetic limb, but she's determined not to give up."
