Kim Kardashian hasn’t been seeing eye-to-eye with sister Kourtney at all this season on Keeping Up With The Kardashians. First, she called Kourt the “least exciting to look at” and made her cry. Then, she fought her about inviting Scott Disick to their Christmas party. She even called her sister “the new Rob!” Now, they can’t even go to a dance class without setting each other off. Watch the clip above to see the drama go down.

Kourtney, 39, attends a dance class and her younger sister decides to tag along. But once the 37-year-old arrives, she declares that she can’t dance, so she’ll just watch. “I’m like, a notorious non-dancer,” she says.

They try to get her to join — it’s just for fun, after all — but she plants her butt on the floor and says, “I make money moves.” Notably, both sisters are wearing heels for this exercise class. Most people would opt for sneakers, but most people aren’t the world’s most famous reality stars.

So Kourtney gets down to business as Kim watches — and criticizes — from her spot on the ground. She tries to convince the KKW Beauty mogul that this will give her great moves for her next Kanye West concert, but the mom is intractable. Understandably, this sets Kourtney off.

“Kim has this inability to let loose,” she explains to the camera. “She’s not even moving. I mean, if she’s just going to sit here and critique us, then she can leave.”

Surely this isn’t how anyone wanted this sibling bonding to end. Will Kim and Kourtney ever get along? Viewers will have to wait and see if these two can put their past behind them.

Keeping Up With The Kardashians airs Sundays at 9 p.m. on E!

Do you think Kourtney has a right to get mad at Kim for not dancing, or should she leave her sister alone? Sound off in the comments!
