Kris Jenner is planning to follow in her daughter's Kim Kardashian footsteps and flaunt her age defying figure by posing for Playboy in the buff at the age of 58.

A source told Heat that the 'momager' has been talking about posing for the magazine for a while now, and since she's in the best shape of her life, she is keen to show it off, the Mirror reported.

The insider added that the bikini shot Jenner posted on Instagram recently was so well received that she's said 'Why not' for the mag. In 2007, Kardashian had made the cover of the iconic magazine after being persuaded by her mother.

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.
