Kourt's ex isn't too thrilled to learn she's moved on.

It's OK for Scott Disick to date someone half his age, but when Kourtney Kardashian does it, apparently there's cause for concern.

In a sneak peek at this Sunday's episode of "Keeping Up with the Kardashian," Kourt explains how her ex flipped when she referred to 24-year-old Younes Bendjima as her "boyfriend" while speaking to Scott.

"Last night Scott called me at like 2 in the morning, which he never calls me late at night ever, and he was just like ranting," Kardashian tells sister Khloe the preview. "Like, 'What are we going in life? What are you doing? What am I doing?' And I'll go, 'What are you doing.' And then he'll say, 'What are you doing, is it any better?'"

Scott, of course, has been, uh, doing 19-year-old Sofia Richie since May 2017.

"By the end of the conversation I was like, 'I have a boyfriend and he's 24 years old. It's not the craziest thing that’s ever happened in the word,'" Kourtney continued. Scott's reaction: "He's like, 'He's your boyfriend?!' And then he hung up the phone."

Looks like Disick will be a big topic of conversation on Sunday's episode, as the synopsis explains that his "behavior takes a turn for the worse after learning that Kourtney officially has a boyfriend."

"Keeping Up with the Kardashians" airs Sundays at 9pm on E!
