Porn star Julian St. Jox says that he, Kardashian, and another female porn star had a threesome at a swingers' party in Los Angeles in 2001, according to RadarOnline.com.

Yep, that was 2001 -- and he's just coming forward with this juicy tidbit.

Something doesn't quite add up, despite the fact that Kardashian had a sex tape at one point, so anything is possible.

But why keep this sexy secret under your hat for so long?

According to St. Jox, Kardashian came to the Wyndham Hotel in Culver City at 11:30 p.m.

St. Jox said, "She wasn't known at the time at all, not like today, but for everyone who frequented these parties, she was interesting because she was a new face."

After the porn star and his date, porn actress Emily Ann, danced with Kardashian, he explains that they got a private room and got down to business.

St. Jox noted, "[Kim] looked like she was enjoying herself very much."

Kardahsian's rep, naturally, shoots down the claim.
