Heather Mills

Heather Mills vows she's ready to hit the dance floor on U.S. television.

 The model-turned- activist, currently divorcing her husband of four years, Paul McCartney, says her decision to compete on the popular U.S. TV series Dancing With The Stars is no publicity stunt.

 Mills, who lost her left leg below the knee in a 1993 motorcycle accident, will be the show's first contestant with an artificial limb. She will dance with a sleeve over her prosthesis to prevent it slipping off, and says she also has a spare if necessary. 

 Heather Mills plans to donate her appearance fee to the animal rights organization Viva.

One of the highest-rated shows on U.S. television, Dancing With The Stars begins its fourth season on March 19.
