The hotel heiress lashed out after Cy Waits flew into a jealous rage during New Year celebrations in Cabo San Lucas, Mexico.
Waits lost his cool after Paris and her younger sister Nicky visited another man's house during their holiday.
Refusing to let the blonde socialite kiss him, he raged: 'I had a good life before you. I had a good life with you, but I want to be me, I want to be by myself. Go back to Leonardo’s house.'
He continued: 'Get the f*** away from me. Get the f*** out of here before I ask security to thrown you out of here.'
US TV viewers got a sneak peek of the shocking footage during Paris's appearance on George Lopez's late night chat show.
The reality TV star held her head in her hands as Lopez showed the preview of The World According To Paris and confirmed she was no longer dating Waits.
'We're not together any more. I love him and we remain really good friends,' she said, tactfully.
'I feel like the relationship ran its course. We’ll see what happens in the future.'
Hilton, 30, first stepped out with Waits in spring 2010, shortly after splitting from TV star Douglas Reinhardt.
