The man who had raunchy sex with Paris Hilton in a homemade video said he had nothing to do with the porn flick’s release and will sue her family for wrongfully accusing him, his lawyer told The Post yesterday.

“I won’t discuss the amount, but we are suing Paris, her parents and [publicist] Siri Garber for defamation,” Marty Singer said of his client, actor/producer Rick Solomon.

“They made it appear that my client engaged in criminal conduct with Paris and wanted the tape out there. He has suffered substantial damage.”

Singer accuses one of Solomon’s pals of swiping the tape.

“The person responsible for the theft . . . [is] not Rick Solomon,” Singer said, “[It] was a friend of Rick’s [who] at some point in time was in the house and took the tape.”

Singer said the pal gave the tape to Seattle-based Internet pornographer Roger Vadocz.

The original tape is close to 45 minutes long, but 31/2-minute snippets labeled “Paris Hilton Sex Tape Samplers” were sent to various media outlets last week.

Singer said that Solomon – the estranged hubby of actress Shannen Doherty – has filed a police report describing the theft and that “police are looking into the matter.”

Solomon’s business ventures include distributing amateur party videos of scantily clad women.

Meanwhile, if the Hiltons hope to stop their daughter’s video dalliances from going even more public, they’re too late.

There were a dozen purported peddlers of the sex tape on eBay yesterday, claiming to have video and digital copies of the romp for sale.

Bids topped $102 for the raunchfest sampler.

Sites all over the Internet were posting dubs of the 31/2-minute romp yesterday, while popular file-swapping services were buzzing with downloads.

“The demand is outpacing the supply right now,” said Eric Garland of Big Champagne – a “Nielsen-like” rating and tracking system for the Internet.

“Paris Hilton is No. 1 on the file-sharing services right now.”

She’s a hit with Hollywood types, too.

“Everyone in Los Angeles has a copy,” one public-relations big said.

Stars with copies include Pamela Anderson, who was once featured in her own X-rated videoed romp with then-hubby Tommy Lee.

“Pamela saw the video and loved it,” a source said.

And even bad-girl actress Doherty scooped up the tape of her estranged hubby with Hilton.
