A man who claims to have a sex tape featuring Kris Jenner wants to sell it for a million dollars.

The mystery guy, who called himself "Troy," intends to contact Vivid Entertainment - the porn studio who has released many x-rated celebrity videos, including one of Kris' daughter Kim Kardashian and her former boyfriend Ray J - to sell them the footage.

When asked why he had not yet offered proof of the tape's existence, Troy said, "I am not [making it up]... I have the sex tape on my hard drive. It goes for a high price. I just can't release a sex tape. It is a million dollar sex tape."

Kris has denied the footage - which Troy claims was shot in the Beverly Hilton hotel - exists and has called police to claim she is being bombarded with calls, voice mails and text messages about the film.

And while Troy confirmed he has made "hundreds" of calls to the Keeping Up with the Kardashians matriarch, he insisted he hasn't harassed her or tried to extort money: "That is absolutely true, yes I have [called her]
''She knew about this sex tape and did not want it out. It was about the sex tape and she doesn't want it out, so yes, I have contacted her lots of times." When discussing reports of extortion, he added, "That is totally false. Nobody has extorted money or asked to extort money from her. There is no money exchange."

Kris - who split from husband Bruce Jenner last October - is now said to have "drastically stepped up" security and was particularly upset over a recent incident where she went out to eat at Malibu restaurant Nobu and then "got a text from the man saying 'Are you enjoying the restaurant?'" The source added, "This person knew where she was."

However, Troy said, "That's an absolute lie. She told me she was going to Nobu in Malibu and I quote unquote I asked her, 'How are you doing at Nobu?' Nobody said, 'How are you doing at the restaurant?' She told me she was going to Nobu. She's a liar."
