"She has this vision of no sugar or no disgusting chemicals in candy. It’s like a completely sugar-free, gluten-free, party-free, fun-free zone because Kourtney has decided that it just doesn’t make sense," she continued in a confessional.
As expected, Kourtney— who refused to make eye contact and, quite frankly, seemed very disinterested in what the mum-of-four had to say— hit back.
“There’s just better solutions to your dated candy that’s literally food colouring that gives people diseases."
Their fight reached fever pitch when she mentioned the theme wasn't on-brand for Kourtney.
“My brand is not unhealthy,” Kourtney said before Kim savagely replied: “This is about a kids’ party. This is not about your brand....Then why does your car have leather seats? Why are you wearing plastic glasses?"
“I just don’t understand why Kim isn’t trying to compromise at all and she doesn’t feel guilty about giving not only her kids and my kids, but all these kids coming to the party so much junk and candy. It’s such a dated vibe to be like that,” the mum to Reign, Penelope and Mason concluded.
Their argument follows rumours the pair continue to be at odds, with an insider recently claiming tension between the pair continues when the camera stops rolling.
"They can't be in the same room together," a well-placed insider told Radar Online of their strained dynamic. “Kourtney has hated Kim for a couple of years now. She thinks she’s vapid and nasty."
“Their egos have clashed big time and when the cameras aren’t on, they don’t speak, “ the source continued. “There are hints of their feud, of course, but the reality is they genuinely can’t stand each other.”
While the source said Kourtney "has much better things to do with her time than kiss up to Kim," the wife of rapper Kanye West believes her older sister should appreciate her more, seeing as Kourtney would "be nobody without her".
Earlier this week, when faced with a question about why they're constantly bickering, Kourtney finally opened up about their strained dynamic.
"It's up and down a lot," Kourtney of their connection before the journalist asked why both Khloe and Kim were deaths staring at her. "Because they gang up on me all day," she angrily added before Kim interjected, admitting: "Welcome to my life. That's what you did to me my whole life until two years ago."
