Heather Mills is recuperating in an Austrian hospital following a skiing accident, the Associated Press reports.

Sir Paul McCartney's ex-wife was reportedly training for the 2014 Paralympic Winter Games. (The former model lost the bottom portion of her left leg in 1993 in an accident and now walks with the aid of a prosthetic limb.)

Mills, 43, fractured her right shoulder blade after crashing on Moelltaler glacier on Wednesday. A hospital spokesman said Mills was released Thursday morning and is expected to make a full recovery.

Mills was married to the former Beatle, 68, from 2002 to 2008; she was awarded $48.6 million in their divorce settlement.
