Kris Jenner calls cops after getting 'extortion' calls over sex tape

Kris Jenner called the cops after she was reportedly being asked to shell out some dough by an unknown individual if she wants her "sex tape" to stay away from the media glare.

According to TMZ.com, the 'Keeping Up With The Kardashians' star has been getting hundreds of voicemails and messages from a caller who has threatened to give it to the gossip site so they can post it online.

Jenner said that the calls amount to extortion and the police are now looking into the matter.
