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."
