Kris Jenner has called police about an alleged blackmail plot involving a sex tape.
The 58-year-old businesswoman - who split from husband Bruce Jenner last October after 22 years of marriage - is reportedly being contacted multiple times a day by an individual who claims to have X-rated footage of the Kardashian matriarch, but she insists no such film exists.
According to gossip website TMZ, Los Angeles County Sheriff's Deputies went to the star's house on Tuesday (25.03.14) and took a report, which says Kris has been receiving up to 300 phone calls, voice mails and texts a day for the last few weeks from the person who is threatening to expose the compromising footage.
Kris also claims the caller has at times changed their story to insist it is actually her daughter Khloe Kardashian - who is in the process of divorcing disgraced sportsman Lamar Odom - featured in the tape.
The brunette beauty - whose daughter Kim was propelled to stardom by an X-rated video she recorded with ex-boyfriend Ray J - previously confessed she and Bruce made their own pornographic movie to ''spice things up'' between them.
