The whole world suspects 60-year old Kris Jenner was responsible for ‘leaking’ THAT sex tape of daughter Kim Kardashian to catapult their family to stardom back in 2007.
It certainly paid off for Kim but will it be a case of like mother, like daughter?
Ten years on from Kimmy's exposé, rumours abound that home movies of Kris and her late husband Robert Kardashian are being passed around in a bidding war.
According to biographer Ian Halperin, the X-rated footage reveals a lot more of Kris than happy snaps at a family barbeque.
Halperin claims writer Jackie Collins spilled the beans on Kris and Rob's sex life before she died last year.
He told the Sun: "The last time I saw Jackie was in spring of last year, at The Grove in LA.
"I told her I was working on a Kardashian book and she was very excited.
"Jackie was infatuated with the Kardashians' success and said if it was not for Kim's sex tape they wouldn't have got a TV show."
He went on: "She claimed the Kardashian family were no strangers to sex tapes and said Robert Kardashian, whose hobby was photography, used to film some of his dalliances and extra-marital affairs on video cameras."
A source now claims the Robert Kardashian porn collection is making the rounds in Europe and China because the saucy footage can't be released in the US without consent.
Whispers of seven-figure sums suggest the 20-year-old tape is bound to show more of Kris than we bargained for.
The momager recently tweeted a happy birthday message to daughter Kourtney, who turned 37 on 18 April.
The pic of Kris, Robert and baby Kourtney would have been snapped a few years before the alleged sex tape was made:
