The 37-year-old reality tv star was filmed lounging around with Kris, Kourtney and Khloé when Kourtney said to Kim, "When you sit down your butt looks so huge."
To Kourtney's surprise, mother Kris Jenner snapped at her daughter saying that comment wasn't "very nice."
"She likes having a big butt, I'm not saying anything offensive," defended Kourtney.
However, Kim shocked her family by revealing, "No I don't! I cry about it daily."
Judging by Kim's social media presence, she appears to be fine with flaunting her backside and is frequently snapped at the beach in butt-baring bikini bottoms which the star seemingly happily posts to her account.
Most recently, the mother-of-three appeared in husband Kanye West's Yeezy campaign where she is snapped laying on a bed wearing just a pair of Yeezy sneakers and a small pair of underwear.
Most notably, Kardashian West "broke the internet" in 2014 when she was photographed for Paper Magazine. In the images, Kim is snapped pouring champagne into a glass that was resting on her butt as well as snapped removing her outfit to reveal her backside.
