Kim Kardashian got into the intimate details of her sex life with none other than her grandmother, Mary Jo "MJ" Campbell, in the latest episode of "The Kardashians."

Although they split over the summer, Kardashian is still dating Pete Davidson in the newest season of her Hulu show, and the reality star did not hold back on sharing sex details with her extended family.

"Pete and I were staying at the Beverly Hills Hotel last weekend and we were sitting in front of the fireplace just talking for hours and I was like, ‘My grandma told me that you really live life when you have sex in front of the fireplace,'" she shared with her mother, Kris Jenner, sister Khloé Kardashian and her grandmother.

"And so we had sex in front of the fireplace in honor of you," Kardashian shared with Campbell.
