The Kardashian sisters have definitely had fights over Scott Disick before...but not in this way!
In this sneak peek from Sunday's episode of Keeping Up with the Kardashians, Kourtney Kardashian and Kim Kardashian get in an argument over Scott's sudden interest in helping Kim out with baby preparations.
"I love how you don't do this at our house," Kourtney says in response to Scott helping Kim put together strollers, cribs and baby gates. Kris Jenner jumps to Scott's defense, saying, "He's just trying to be helpful," but Kourtney doesn't want to hear it: "Stay out of it," she warns Kris.
Any fan of the Kardashians can tell you that Scott has been a divisive subject between Kourtney and her sisters, and even Kris. But in the past, the arguments were always over whether Scott was "good enough" for Kourtney...not over whether he was being too nice to Kim!
Is Scott just paying for his past, when he neglected to help Kourtney out with baby preparations as much as he could have? Or is Kourtney overreacting because she's jealous, as Kris implies?
Meanwhile, Kim is moving into Kris' house for a few months while she has the baby...but there's no telling if Kim will be able to handle the stress of moving back in with mom.
