LATEST: Paris Hilton has dismissed Tom Sizemore's claims he slept with her when she was a teenager, insisting she has never even met the troubled actor.

In an interview on his new porn tape THE TOM SIZEMORE SEX SCANDAL, the SAVING PRIVATE RYAN star says he enjoyed a one night stand with the then 19-year-old Hilton when she begged him for sex after a party.

Sizemore goes on to allege hotel heiress Hilton showed him a good time, adding, "She knew what she could do to people."

But Hilton, now 24, is appalled by the suggestion she had sexual relations with the 44-year-old, who has been in and out of court fighting drug and domestic abuse charges over the last two years.

She tells 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."
