Troubled movie star Tom Sizemore claims he has bedded Paris Hilton when she was a teenager.

The SAVING PRIVATE RYAN star, who has been in and out of court fighting drug and domestic abuse charges over the last two years, is the star of Vivid Entertainment's new sex tape THE TOM SIZEMORE SEX SCANDAL.

The video features the self-proclaimed sex addict having "inexhaustible sex" with up to four young women at a time.

But, even more shocking is what the 44-year-old actor says about an alleged one-night stand with socialite Paris Hilton in 2001 - when she was just 19.

He claims Hilton stayed behind after a party he threw and suggested quite explicitly that they have sex together.

Sizemore alleges that the heiress showed him a very good time, adding, "She knew what she could do to people."

The actor recalls Hilton left "abruptly" in the morning, climbing into a long limousine with the parting words, "Goin' to Sundance. See you next week."

During the candid interview on the sex tape, Sizemore also praises ex-fiancee Heidi Fleiss' business sense and reveals the depths of despair and depression he went through during his recent legal proceedings.

The actor also claims he started taking crystal methamphetamine in a bid to relieve his depression.

He also reveals he has a condition known as priapism, which causes an involuntary prolonged erection that allows him to perform intercourse for unusually long periods of time.

Sizemore was recently ordered to attend an inpatient drug rehab clinic in Los Angeles, and yesterday (17OCT05) he was handed probation for three years.
