Paris Hilton has hit back at Tom Sizemore's claims that he bedded her when she was a teenager.

The socialite not only denies sleeping with the Saving Private Ryan star, she says he "is not an acquaintance of mine".

Mr Sizemore reckons that he enjoyed a one night stand with Paris when she was just 19.

In an interview on his new porn tape The Tom Sizemore Sex Scandal, he reveals how Paris begged him for sex.

The 44-year-old, who has been in and out of court fighting drug charges over the last two years, says they met at a party and that Paris went on to impress him in the sack:

"She knew what she could do to people," he claims.

He reckons that Paris left early the next morning, jumping into a limo with the words: "Goin' to Sundance. See you next week."

But 24-year-old Paris has rubbished Tom's chat, telling website The Scoop:

"It's disappointing that Mr. Sizemore has to use my name to sell his DVDs.

"He is not an acquaintance of mine, nor have I ever had intimate relations with him."
