The charity campaigner, Sir Paul McCartney's former wife, was last month offered a trial place on the development squad of the British Disabled Ski Team as she continues to pursue her dream of competing in Sochi.

The 43-year-old former model, who lost part of her left leg when she was hit by a police motorcycle in 1993, sustained the injury to her leg when skiing during a 24-hour race.

She tweeted: "In Austria for the Schladming night race, can't ski though as injured good knee in charity 24 hr ski race when public were let on the race track whilst skiing 100 kmph + Should be good to ski again soon. [sic]."

Mills had been taking part in the event which coincided with the FIS Men's Alpine Skiing World Cup event in Schladming.

It is not her first sporting injury - last year she fractured a rib in TV's Dancing On Ice.

Mills' unlikely attempt to qualify for Sochi in 2014 is being taken increasingly seriously, although she admitted herself she still needs to do a lot of work.

"Nobody is on the Paralympic Team until three months before those Games," she said.

"If you're lucky enough to get on the team, which I am, you get a trial for a year.

"If I managed to compete, it would be phenomenal - very inspiring for all the kids that I counsel.

"They didn't believe they could do anything and now they are trying ice skating and rollerblading and biking and swimming, which is wonderful.

"Having loved sport my whole life, competing in a Paralympics would be a dream come true."
