But the reality star wasn't always a fan of her behind!
In another clip from the episode, Kris opens up about growing up with a "big booty" and why now she fully embraces her killer curves.
"Well it's probably in my genes because back in my day, when I was in high school we tried to hide it!" she revealed. "It's like I had a big butt and it wasn't a good thing and now in this generation it is a good thing!
"I wish it was like a positive thing when I was going to school," she adds.
