Leave it to the Kardashian family to always surprise each other, even when it comes to having sex with their boyfriends.

This is exactly what happened to Khloe Kardashian when she and her sister Kim Kardashian visited their mother Kris in her home. Hollywood Life reported that the siblings were chilling downstairs, and then they suddenly hear clapping sounds, then the headboard hitting the walls. And just after things got silent, they heard more sounds from upstairs, pushing the two reality stars to leave. The 31-year-old Kardashian was left traumatized.

However, this was not the first time she has heard their mother getting intimate. When she was just a kid, she has heard their 51-year-old mother having sex with Bruce Jenner, now known as Caitlyn. Xpose reported that for some reason, she found herself under their parent's bed, and the then couple went at it, and she could not leave until it was over.

Sadly, Khloe does not approve of her mother's relationship with the 34-year-old Corey Gamble. In fact, she finds it absolutely disgusting and weird, which is understandable considering that she grew up looking up to Bruce Jenner as the father figure of their family.

Despite all these family awkwardness, the family still keeps it together as a unit, with the different ladies of the family getting together to celebrate the birthday of their matriarch, Mary Jo Shannon. The Daily Mail UK reported that Kim, Khloe and Kylie decided to celebrate their grandmother's birthday by posting several pictures on Instagram depicting throwbacks and photos snapped during the celebration. Even baby North posed for the camera, showing how she looked much like Kim did when she was her age.

The Kardahsian family might be a little kooky and crazy when seen through their reality show, but no one can deny the fact that these lovely women do keep each other close. Overall, after all the crazy controversies, their tight-knit family can be deemed jealous-worthy.
