London, Nov 9 Heather Mills has almost decided to pull out of Dancing On Ice before the show even begins because of severe pain in her stump, it has emerged.

The 41-year-old Mills is one-legged and is believed to have told bosses that she is "struggling" even during the rehearsals, reports the Sun.

The ex-wife of Beatle Sir Paul McCartney, Mills has trained for the ITV1 show beginning in January, for almost three weeks.

Although, she had been completely at ease with grooving on America's Dancing With The Stars in 2007, ice-skating is proving difficult for her.

"Ice skating is much more demanding," the Sun quoted an insider, as saying.

The source added: "Heather is suffering a lot of pain." (ANI)
