Kourtney won that fight when she slapped the foundation clear off kim’s face.
The backstory : Basically Kim and Khloe have been calling Kourtney lazy. They said she has nothing going for herself like the rest of them. Kim said kourtney was the least good looking one out of all of the sisters and that no one is checking for her. Also, Kourtney does not discipline her kids and that she lets them walk all over her. Lastly, Kim said that Kourtney doesn’t want to pay her half on the trip that they went to for north’s birthday. Kourtney said she shouldn’t have to pay.
