The company said the DVD titled "Kim Kardashian Superstar" should be in stores by Feb 28. It will also be available online on the same day at www.vivid.com or www.kimksuperstar.com and will include additional footage not on the DVD.

Vivid co-chairman Steven Hirsch said the company obtained the video from a third party but did not identify the person or entity. "We are comfortable that we have the legal right to distribute this video, despite what others may say," says Mr. Hirsch.

"I've seen the video and it's really great," says Mr. Hirsch. "It has over 30-minutes of explicit sex that fans of erotica will find very appealing featuring two young and glamorous high profile celebrities. Apparently, the video was shot by Ray J about three years ago when he and Kim were in a relationship. The production is crystal clear and viewers will definitely get their money's worth. If either Kim or Ray J would like to discuss the video with us we would be happy to do so," he added.

A rep for Kardashian said, "Are you [bleep]ing me? Kim is going to die . . . are you sure?" Later, he added, "She will be taking legal action against anyone responsible for this. She was unaware of this and caught completely off-guard."
