Heather Mills' alleged outburst left the head of the Paralympic alpine skiing committee "extremely shocked and upset", according to a spokesman for the sporting authority.
"Heather's aggressive behaviour and verbal abuse has left Sylvana [Mestre] extremely shocked and upset," said Craig Spence, the International Paralympic Committee's Director of Communications, in a statement.
"Para-athletes are role models and an inspiration to billions of people around the world. This disgraceful outburst is not what we expect from any athletes competing in our competitions and will not be tolerated."
Mills claims Mestre shouted at her, with her management team accusing the IPC of waging a "vendetta" against her.
The IPC said the incident involving Mills and Mestre was witnessed by a number of people, and insisted Ms Mestre was just trying to enforce the rules and offer the former model a solution to the issue.
"There can be no excuse for such aggressive and intimidating behaviour towards such a highly respected and experienced official within the Paralympic Movement."
The British Paralympic Association has said they were "saddened" by Heather Mills' withdrawal from the selection process for the 2014 Sochi Paralympic game following a dispute with the International Paralympic Committee (IPC) over her adaptive equipment.
The IPC have since accused Mills of "harassing a Paralympic official" after the decision, however the former model's spokesman claimed there was a "vendetta" against her.
In a joint statement, the British Paralympic Association and British Disabled Ski Team said: "The British Disabled Ski Team were informed by IPC Skiing that there was an issue with the adaptive equipment that Heather Mills was using that needed to be addressed before she would be allowed to compete.
"As a result of this and on the back of an injury, Heather Mills has decided to resign from BDST, thereby removing herself from the selection process for the Sochi Paralympic Games.
"Occasionally in sport equipment issues arise, especially with adaptive equipment and the interpretation of the rules in relation to its use.
"Therefore we are all saddened that she has decided to retire at this stage, rather than working with BDST and IPC Skiing to resolve the issue."
