Mills, a 2013 World Cup ski slalom silver medal winner, was at a team captains' meeting when International Paralympic Committee official Sylvana Mestre explained her equipment was unsuitable for the Paralympics. The former model and actress then lunged at Mestre, allegedly calling her a bitch and saying, "you don't know who I am, I will make your life miserable."
Mills's team recalled a different version of the events, in which Mestre was portrayed as verbally berating Mills before storming off. Her coach, John Clark, went so far as to claim that there is a "vendetta" against Mills.
The debate is centered around Mills's adaptive ski equipment. The former model requires an adaptive ski boot that must be approved for competition by the IPC. During the meeting, Mestre claims she was "trying to explain to her that this is not the equipment we approved earlier in the year and then that was it, she exploded."
Mills lost part of her left leg in a 1993 motor accident and gained notoriety for her use of a prosthetic during her modeling career and her ill-fated marriage to McCartney.
