Sir Paul McCartney's ex-wife Heather Mills has denied she hit a member of the International Paralympic Committee (Ipc) during a heated bust-up in Austria.

The former model, who had hoped to compete with the British ski team at the Paralympic Winter Games in Russia next year (14), was accused of throwing a "tantrum" and yelling at Ipc executive Sylvana Mestre after she was told her equipment breached regulations.

Other witnesses allege she grabbed Mestre during the confrontation at an Austrian hotel on Monday (16Dec13), but Mills is adamant the bust-up never became physical, saying, "I never physically touched her... she's never made a statement saying I physically harmed her... These reports saying that I hit her are just tabloid rubbish."

Mills pulled out of qualifying heats for the games in Sochi after officials told her she would not be able to compete using her preferred equipment as it breaches competition regulations.

Ipc bosses have confirmed they are considering taking disciplinary action against Mills following her outburst on Monday.
