Kourtney Kardashian is said to have broken up her mother Kris Jenner and her longtime boyfriend, Corey Gamble’s relationship.

Word is Jenner, 60, was “humiliated” after Gamble, 37, started getting extra close with Kardashian, 35.

“Kris has already told Corey he’s out,” one insider told OK! Magazine Tuesday. They added that Gamble an Jenner will continue to pretend to date as “they have to go through the motions for the show.”

As for Kardashian, she is said to “feel terrible” about the split.

“She was relying heavily on [Corey] in the wake of Scott’s departure. But Kris is as cruel as she is heartless and she is NOT going to be humiliated like this.”

Meanwhile, Gamble has followed suit when it comes to the famous Kardashian & Jenner clans popping off on paparazzi.

X17 Online Photographers caught up with Gamble and Jenner at LAX and they were determined to snap photos of the famous mom and her beau. But while Gamble is usually pretty laid back, he wasn’t having it that day and ordered the paparazzi to stop.

But what he might not have expected was for one man behind a camera to refuse and yell at him, “I’m not stopping. This is my job dude.”

Gamble proceeded to tell the man to back away from their car and threatened that if he didn’t move, Gamble would have him moved.

But that didn’t seem to impress the photographer as he responded with, “Do it.”

Gamble walked to the back of the truck only to find the photographer getting up close shots of Jenner, who was sitting in the passenger seat on the phone. He confronts the paparazzi and tries to put his hand in front of the camera; threatening to take legal action.

“Do you wanna get sued?” he asked.

Gamble then got into the car and he and Jenner pulled off. But the photographer made sure to snag a shot of that too.

Interestingly enough, Kourtney Kardashian revealed via Sunday night’s episode of Keeping Up With The Kardashians on E! that her oldest son, Mason Disick, likes to throw his own insults at the paparazzi and calls them “fat.”
