Sorry, guys! Kim Kardashian may soon be off the market in more ways than one. A mystery shopper is trying to score all of the rights to the sex tape that made the reality star a household name. Porn purveyor Steve Hirsch received a letter inquiring about purchasing the freaky footage that co-stars Ray J. In the letter, an attorney for the potential buyer writes, "I was approached by a private party who has asked us about looking into the possibility of acquiring all rights of the Vivid, 'Kim Kardashian Sex Tape.' The party we represent does not intend to distribute or broadcast the 'tape,' but hopes to completely remove it from the market." The buyer apparently wants it... and he (or she) wants it now. According to TMZ, the interested party is also coveting any raw, unused footage that didn't make it to the final cut. But don't expect to see a "best of." The lawyer for the interested party adds, "We would purchase any other footage you may have control of that involves Ms. Kardashian." So far, Hirsch has not responded to the inquiries. However, we'd be willing to bet that he's not in any rush to unload the footage, considering the fact that more than 2 million people visited the site that peddles Kim Kardashian Superstar the weekend of her wedding. To put it in perspective, the site usually gets just 300,000 a month. Although nobody is saying if Kardashian is the buyer, nobody is saying she isn't.
