It all started when Kim, Khloé and Kris teamed up against Kourtney, shaming her for not wanting to invite her ex, Scott Disick, to the party. Kris argued that Scott has been a part of their family for 10 years, so Kourtney had to invite him, which caused Kendall to ask, "What about my dad?" An awkward silence fell over Kris, who was clearly caught in her own hypocrisy.
Kim then stated, "Scott has never done anything mean or said anything negative, so that's different," to which Kendall asked, "Is that actually a joke?" Kendall then pointed out that both Caitlyn and Scott have done "f*cked up things in different ways." Kris chimed in saying, "But nobody that's coming would even know how to respond to her because of all the things–" Kendall cut her off there, snapping back, "So the f*ck what? Why are we worried about anyone else? It's the night– even if she doesn't come, it's nice to have–"
While it's no secret that there was a falling out between Caitlyn and the Kardashians, Kendall was just shocked that her mother could not see the comparison between inviting Caitlyn and inviting Scott. Kris told Kendall that the difference was that she has a relationship with Scott, but Kendall immediately called her out, saying, "Oh, you didn't have a relationship with my dad for 25 years?"
So far this season, Kourtney has been distancing herself from the rest of her family because she has not been getting along with Kim and Khloé and, following the drama between Kendall and her mom, it seems like maybe Kourtney will finally have one of her family members on her side. "This is exactly why my sisters and I haven't been getting along," said Kourtney. "They just don't have my back, and they don't take my feelings into consideration. And now I feel like the same thing is happening with Kendall. If it's not exactly what they think, there's always, you know, criticism and judgment, and I'm not here to be criticized every day. I'm so over everyone and their bitchiness."
