Sir Paul McCartney'S estranged wife Heather Mills has been subjected to a barrage of online abuse following her appearance on US TV's Dancing With The Stars last night (19MAR07). Angry viewers have bombarded network ABC's website to criticise the former model - who lost a leg when she was hit by a motorcycle in 1993 - after her debut on the American programme. Mills, who performed alongside professional dancer Jonathan Roberts, received a standing ovation from the show's audience after she completed her routine with a high kick. But viewers posting on the ABC site branded the star "a nobody", and described her dancing "as wooden as her leg". One enraged fan wrote, "I'll vote like crazy to get rid of Heather Mills." And fellow contestant Paulina Porizkova admits Mills' appearance is in danger of backfiring. She says, "If she comes on and shows how warm and wonderful and gracious she is, the people are just going to go for her. However, if she doesn't, she's screwed."
