Putting to bed those Playboy rumours, Kris laughed off reports that she would ever pose nude for the magazine.
'Oh my God, no!' she said. 'I don't think anyone wants to see me without any clothes on.'
'The older you get, the harder it is. I love to work out and love to feel feel like I'm in shape... Last summer I posted those bikini photos because I thought it was so inspirational for someone in their fifties to have some motivation and say 'wow' anybody can put a bathing-suit on.'

The black-haired beauty also dispelled whispers that daughter Kim's wedding to rapper Kanye West in Paris in the coming months could be cancelled because of a rule that says a couple must live in France for 40 days before they can tie the knot.
'As far as Kim and Kanye go, everything is on track and they actually have a place there, they have a house in Paris.'
Kim's wedding number three seems to be all go, however, Kris has yet to see her second eldest daughter's wedding dress and admitted that she doesn't know what the wedding plans are.
She said that Kim wants to do things very differently 'from last time round', with something a little more simple and in keeping with Parisian tradition.
Speaking about what is set to be one of the biggest Vogue covers ever, Kris said it was so 'top-secret' that not even the rest of the family knew about it.
'It was so exciting' to go through it all with Kim and 'watch one of her dreams unfold', Jenner said.

Going from the pending nuptials of one daughter to the marriage break-up of another, Kris admitted, 'Khloe and Lamar are still apart... there is not really any change there that I know of or that I can report. She is just hanging in there and doing her best.'
The news will surely add fire to speculation that the newly single 29-year-old is dating rapper French Montana.
The quick-firing radio presenters also asked about Khloe's Sunrise saga and whether she cut the line after they asked her about her 10-month-old neice North West or if it was an accidental dropout.
Kris laughed that she didn't even hear about the uproar, saying she was probably asleep back in LA.
