Of all the Kardashian siblings, Kourtney and Khloe seem to get along the best. The duo, who are currently starring in the Keeping Up With the Kardashians spin-off series Kourtney & Khloe Take the Hamptons, tend to keep level heads when the drama is heating up with their other siblings (cough, Kim) or momager Kris Jenner.
But in this new clip, the friendly sisters share a tense moment when Kourtney, 35, doesn’t want her longtime boyfriend and father to her two (soon-to-be three) children, Scott Disick, to go out partying with Khloe, 30.
“I really just have no patience while I’m pregnant to deal [with it],” Kourtney explains to a clearly annoyed Khloe. “He just needs to decide if he wants to be a lunatic around town. I just don’t want that around me.”
“So you’re going to break up with him if he wants to be a lunatic?” Khloe asks, to which Kourtney replies, “Yeah.”
Disick, 31, who lost both his mother and father in the past year, has clearly been going through a tough time. The notorious party boy was hospitalized in June for alcohol poisoning before vowing to stay sober until after his third child was born.
“People have passed away from alcoholism, and that’s something that I need to stop right now with Scott,” Kourtney says in the clip. “I’m not going to let that happen to him. I don’t need [Khloe] influencing him to go out.”
