This week, Kim Kardashian has revealed in her sisters telling her she looks anorexic and insinuated that Tyson Beckford must be gay if he doesn't like the way she looks.
Now, in a new trailer for the upcoming season of Keeping Up With the Kardashians, Kim's claws really come out when she slams older sister Kourtney for being the least hot member of the family.
The low blow comes after 37-year-old Kim and 39-year-old Kourtney have a blowup over scheduling a photo shoot for the family's annual Christmas card.
"I need Kourtney to not be so f**king annoying with a stick up her a** like she runs this s**t because she doesn’t," Kim declares. "She’s the least exciting to look at."
In a follow-up trailer released on Thursday, a tearful Kourtney says to sister Khloe about Kim's comment, "Who even speaks like that?"
The 15th season of Keeping Up With the Kardashians premieres on E! August 5.
