Kris Jenner gives NSFW confession about sex life with boyfriend Corey Gamble in major slip up

Family matriarch Kris Jenner made a rare admission about her age gap relationship with Corey Gamble on this week's instalment of The Kardashians, letting slip some candid details about their sex life.

Gamble, 45, and Jenner, 70, have been dating for more than a decade, with their romance often being kept off Keeping Up with the Kardashians as the pair attempted to keep things under wraps, or under the covers.

But the grandmother-of-13's tight lips loosened on this week's Hulu episode, while talking with daughter Kylie, 28, about an apparent ghost in her home.

The younger Jenner complained to her mom that her residence was 'haunted', with the apparition only appearing at night and often making loud banging noises, with no rhyme or reason to when it appears.

This prompted her mom to let loose in the confessional, hinting at her sex life with Gamble by saying wryly: "If anyone gets that the ghost has a schedule, it’s me." And she didn't stop there.

The 70-year-old 'momager' then elaborated on how her love life resembled Kylie's ghost, adding: "Some nights you’re in the mood to bang, and some nights you’re not."

One of the show's producers followed up by asking if she was still talking about the ghost, or her sex life.

She thought about it, responding: “I don’t know. Probably both."

The pair met at an Ibiza birthday bash for designer Riccardo Tisci in 2014, just months after breaking up with Caitlyn Jenner and before she had finalized the terms of their divorce.

Just last month, Jenner celebrated her younger boyfriend's 45th birthday after break-up rumours with an effusive message on Instagram where she described Gamble as her 'ride or die'.

She said: "Thank you for all you do every single day, for the love you give, and for always being there for all of us. I’m so blessed to have you by my side. I love you!!!"

Last year, Jenner gave further insight into her age-gap passion and how the couple made it work. She said on The Kardashians: "I used to say to Corey all the time when I first started dating him, like, 'Why do you want to date somebody who is older than you?'

"I didn't get the age gap, and then he taught me that age is just a number. It's a f**king big number, but it's a number!"

Their decade-long relationship fitted into both of their lives smoothly, with Gamble's experience as Justin Bieber's former manager granting him insight into the upside-down world of the uber rich and famous.

Most importantly for Jenner: "He doesn't try to control you."

"He knew all about security and all about all the drivers and seemed to know everybody in L.A. and everybody in my life," Kris explained in a March episode of Khloe in WonderLand. "It was a very safe feeling to be able to date someone who you didn't have to explain how our life worked."
