Celebrity amputee Heather Mills is terrified about performing on TV talent show Dancing With The Stars next week (beg02APR07) because she'll be jiving on one leg. The estranged wife of Sir Paul McCartney came through the first two weeks of the dance-off unscathed, but fears she'll struggle with next week's dancefloor challenge. She says, "I'm worried about next week; I've got to do the jive - you try and hop on a leg that's like concrete and the other leg bounces up and down like a trampoline." Mills stunned US viewers and show judges this week (beg26MAR07) when she performed a backflip during her routine with professional dancing partner Jonathan Roberts.
