In one confessional, Koko called Kourt and Cor “conjoined twins.”

“Do you find it bizarre with how close Kourtney and Corey are?” Kim asked the 31-year-old. “It’s weird.”

Later in the episode, Kim confronted Kourtney about the friendship, though Kourt simply encouraged her sister to get to know the 35-year-old.

Eventually, Kim and Corey bonded — and she learned that he didn’t grow up with a big family like the Kardashians, which explains why he gravitates towards Kourtney and her kids.

“I hear about Corey’s life and it makes me feel very lucky to have such a big family,” she told the camera. “To find someone that just kinda fits in, and is so chill, and goes with the flow is, like, really I think a blessing to my mom.”
