The former glamour model has worn a prosthetic limb since her left leg was amputated following a motorcycle accident in 1993.
She has been in rigorous training for the hit series, but has been struggling with some moves because of her disability.
Earlier this week (begs25Jan09), Mills was forced to halt rehearsals to get a new limb fitted.
She reveals, “It’s really coming out of the socket. The more steps we do it comes out and then has to go back in. The screw might have loosened. I’m excited because I have a new leg. Every time you get a new leg you’ve got to get used to the different alignment and how it feels. I was trying to do my moves and kept falling over.”
But Mills visibly struggled with the new limb on Sunday’s live show as she skated to The Emotions’ Best Of My Love.
After her performance, she said, “I had to adjust my leg because it keeps slipping out but (my physiotherapist) Sharon’s been brilliant and glued it in. When you sweat the glue starts to move.
“I’m glued in now otherwise I wouldn’t be able to skate. We’re going to get a new socket made.”
TV chef Gordon Ramsay’s wife Tana was voted off the show, after scoring just 12 points out of a possible 30 from the judges.
