On Friday (September 21), it was reported that West was filmed in a hotel room with a Kim Kardashian lookalike, who is allegedly 18 years old. West is currently dating Kardashian, and the tape is believed to have been made before they got together.
West's lawyers issued a cease and desist notice relating to the alleged footage on Sunday (September 23) since it violates West's "rights of privacy and publicity", reports All Hip-Hop.
The musician's lawyers have also said that "the screen shot, as well as the tape from which the screen shot was taken, were illegally obtained and [are] believed to have been stolen from Mr. West's computer".
"We hereby demand that you... immediately cease and desist from posting, advertising, marketing, displaying and disseminating the illegally obtained screen shot of Mr West," the statement added.
Due to the high demand of the sex tape, West's lawyers are apparently seeking any information on the anonymous person who is shopping the footage, which Sex.com has reportedly offered to buy for $1 million (£616,532).
