In the teaser for the episode set to air Dec. 29, the rapper (sans his shirt) and the reality star (who is rocking a leopard print pajama top) are in bed together as she makes fun of him. It turns out French Montana has a belief that the film Plant of the Apes was stolen from him.

This is something that Kardashian not only thinks is ridiculous, she and Scott Disick can't help but laugh at his theory.

"You know they stole my monkey name and made a movie about it? My monkey name is Julius Caesar bro. Julius Caesar is a Roman god, it's not a monkey."

Kardashian then pointed out that not only is the movie a hit, but French Montana is not the originator of Julius Caesar. Still, Disick goes along with the joke and suggests to French Montana that he take legal action and sue.

French Montana then replies, "I'm gonna have to talk to my monkey about that. Matter of fact let me call my monkey and put him on FaceTime."

Aside from her boyfriend thinking a major movie idea was stolen from him, Kardashian laughs hysterically at the idea of French Montana calling his monkey for a video chat.
