A Kim Kardashian Exclusive

In an exclusive conversation with TMZ, Kim Kardashian claims that she has nothing to do with the sale of a raunchy sex tape ... but she isn't denying it exists.

"There is no tape being shopped," Kim said. Paris' BFF added, "Ray J and I remain friends, and there is nothing he would do to spite me."

As TMZ first reported, Kardashian and Ray J, Brandy's bro, made a tape during their relationship that is being shopped to several adult video companies. One source, who has seen the tape, claims it features oral sex and water sports.
