Kourtney and Khloé Kardashian are currently starring in the Kardashian franchise series "Kourtney & Khloé Take the Hamptons," where the dynamic duo get along well and manage to keep sensible while dealing with the drama of other siblings and momager Kris Jenner.

But Us Weekly reports that the friendly sisters shared a tense moment while filming "Kourtney & Khloe Take the Hamptons" when Kourtney, 35, confronted Khloé, 30, about partying with her longtime boyfriend and father to Mason, 4, and Penelope, 2, Scott Disick.

And there's good reason.

TMZ reported that Disick was hospitalized for alcohol poisoning on June 22, the night of his birthday bash at the 10AK Nightclub in the Hamptons. The poisoning occurred days after Kourtney threw Disick out of their Hamptons rental home. While Disick was hospitalized, Kourtney took the kids to celebrate niece North West's birthday in California.

Since then, Disick has promised to stay sober, at least until after Kourtney gives birth to their third child. He is reportedly eceiving counselling from Pastor Rich Wilkerson Jr., the minister who married Kim Kardashian and Kanye West.

Despite the promise and counseling, Disick was photographed holding a wine glass while partying with rappers Fat Joe and French Montana late July.

"I really just have no patience while I'm pregnant to deal [with it]," Kourtney explains to an annoyed Khloé on an episode of "Kourtney & Khloé Take the Hamptons." "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?" Khloé asks.

"Yeah," Kourtney replies.

This past year, Disick, 31, lost both his mother and father.

"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 [Khloé] influencing him to go out."
