Mills previously appeared in the US series Dancing With The Stars
Sir Paul McCartney's ex-wife Heather Mills has been voted off ITV1 show Dancing on Ice after losing out to actor Kieron Richardson.
Mills - who has had difficulty doing some of the skating moves because of her prosthetic leg - said she was glad her efforts had encouraged others.
"I'm so excited that all the kids that have lost limbs are now going out to skate," she said.
The lowest mark in the main competition went to GMTV's Dr Hilary Jones.
He got 11.5 points out of a possible 30, although some of the judges said his performance was more solid than last week's.
The judges said the skate-off between Mills and Hollyoaks star Richardson "couldn't be closer" but four out of five panellists voted to give Richardson another chance.
Former Emmerdale actress Haley Tamaddon received the highest score of the night, despite her professional partner tripping on the ice, which caused the pair to take a tumble.
Nine couples will return to skate in next week's show.
