According to Kim Kardashian, she might be: on this Sunday's episode of Kourtney & Kim Take Miami, Kim offers Kourtney a dire warning about the way she's treating Scott.
When Kourtney can't find Scott around the house, she asks Kim for his whereabouts. Kim responds with some serious tough love, jumping on Kourtney for not spending any "alone time" with Scott.
"He just feels like you only care about the kids," Kim explains. But Kourtney is unfazed: "They are my first priority," she responds.
That's when things take a turn: Kim accuses Kourtney of "ditching" Scott, and warns, "He's going to cheat on you and it'll be your fault."
This season, we've seen a new Scott Disick in Miami and watched as he and Kourtney seem to be getting along better than ever. But could Kim be right? Is there trouble on the horizon?
Tune in to E! this Sunday at 9/8c to find out on an all-new episode of Kourtney & Kim Take Miami.
