Dancing On Ice celeb Heather Mills has said that training for the show is “20 billion times harder” than training for US show Dancing With The Stars.

Speaking on GMTV, the 42-year-old promised a “spectacular” routine for Sunday’s show, but warned there was a risk of her skating partner Matt Evers “flying into the audience” if things went wrong.

“It’s about 20 billion times harder so unless you’re willing to really put in hours and hours and hours of training, way beyond anything like the dance show, it is the hardest thing,” Mills said.

Evers, meanwhile, described her as “inspirational”, saying she was willing to try any moves as long as he proved it could be done on her artificial leg.

“Every time Matt asks me to do something I say ‘OK, do it like you can’t move your ankle, and you can’t move your feet like you do with your own feet, and keep your leg straight’,” Mills revealed.

“If he manages to do that, then I say ‘right, let’s do that, let’s try that’. So I’ll try absolutely everything. I might not do it very well but I’ll try it.”
