Are Kris Jenner and Corey Gamble the next celebrity couple who are going to break up? The momager is reportedly ready to dump her boyfriend, who is 25 years old her junior, because he's getting closer to her daughter Kourtney Kardashian and she's "humiliated."

"Kris has already told Corey he's out," a source tells OK! Magazine. According to the site, their split is just about time as now they still "have to go through the motions" for the family's reality show "Keeping Up with the Kardashians".

Kourtney has reportedly been relying heavily on the 35-year-old music executive since her split from longtime partner Scott Disick. "Kourtney feels terrible as she was relying heavily on him 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," the source adds.

Additionally, the Kardashian-Jenner matriarch is said to be losing interest in their sex life. "It was exciting for a time, but Corey's the youngest guy she's ever been and she didn't like being the one constantly worried he'd stray," the source continues to dish on. "When she loses interest in the sex, that's the end of things as far as she's concerned."

And there's another thing that may cause the 60-year-old reality TV star to lose interest in her toy boy. She's "come to miss having an adoring downtrodden 'yes' man like Bruce [Jenner] was," the source says.
