Kim Kardashian warns sister Kourtney she will lose Scott Disick

In a preview for an upcoming episode of Kourtney And Kim Take Miami, Kim Kardashian was giving relationship advice to her sister Kourtney.

Kim Kardashian, 32, can be seen telling her older sister that Scott Disick is going to cheat on her if she doesn’t show him more affection.

The reality star only adds insult to injury when she then claims that should this happen, it would be entirely 33-year-old Kourtney Kardashian’s fault.

Kim Kardashian gives the warning out of the blue after Kourtney unsuccessfully attempts to find Scott Disick and asks Kim if she knows his whereabouts.

“He took the boat out,” Kim Kardashian says while reclining on her bed and barely glancing up from her computer screen.

“I think he’s just kind of trying to, like, do his own thing.”

The reality star adds: “He just feels like you only care about the kids.”

Kourtney Kardashian unapologetically states that the couple’s two children, Mason and Penelope, are her first priority, but Kim is having none of it.

“You don’t want even alone time with Scott,” Kim Kardashian chides.

“It’s weird.”

Kourtney Kardashian continues to stand up for herself but it’s clear she is growing increasingly concerned.

“For me, I like doing stuff all together as a family,” she explains.

“He’s gonna cheat on you and it’ll be your fault,” Kim Kardashian hits back.

“You just don’t put in any effort. You’re going to lose him. No joke.”

In case she hadn’t drummed her point in enough, Kim Kardashian adds: “You’re literally going to end up, like, alone.”

After attempting to shrug off her sister’s cruel prophecy, Kourtney Kardashian later admitted her concerns to the camera.

“Just hearing Kim say those words really just freaks me out,” Kourtney Kardashian said.

“Not that Scott would ever cheat on me, but I just really don’t want this for my relationship.”

The new episode of Kourtney and Kim Take Miami airs on Sunday at 9 p.m. on E!.
