Sir Paul McCartney's estranged wife Heather Mills is surprised by the positive response her appearance on US TV show Dancing With The Stars has provoked. Mills, who is currently engaged in a bitter divorce battle with the former beatle, is pleased her status as a dancing amputee is proving an inspiration to viewers. She says, "I wanted to show what I could do, to take the stigma away from the disability. "But I'm touching people I didn't expect to touch."
