Paris Hilton has been forced to deny claims she was involved in a lesbian sex show.

The hotel heiress - who became the unwitting star of her own homemade sex tape after ex-boyfriend Rick Salomon leaked footage of their romps onto the internet in 2004 - is furious with allegations made by Elizabeth Jawhary suggesting the pair stripped for wealthy men in Las Vegas.

Talking about her time with Paris, Elizabeth claims in new book 'Six Degrees of Paris Hilton': "We partied pretty hard. Some men would pay for girl-on-girl action. I'd be there. And they'd pay to watch.

"One night Paris joined in and got naked, and the girls would get naked."

Elizabeth says she would be paid around $5,000 for a private show but claims she never saw Paris take any money.

Paris' representative has dismissed the story as "totally untrue and a complete fabrication".

The 28-year-old socialite recently spoke about the horror she felt when she discovered her sex tape - which was later released as a DVD entitled '1 Night In Paris', which she received a share of the profits from - with Rick had been leaked.

She said: "When I heard about it I thought, 'Yeah right. It's going to be a look-a-like. It's going to be a joke.'

"But a couple of hours later it was everywhere online and then I saw it.

"It's the most intimate thing you can do and the whole f***ing world is watching it and laughing at you."
