Kris Jenner Admits Corey Gamble's 'Yellowstone' Casting Sparked Her Jealousy, So She Forced Him to Reject Role

Though Jenner was not in favor of her boyfriend having to potentially kiss another woman on the series, she admitted on Thursday's 'Kardashians' season 4 premiere that she'd definitely kiss Kevin Costner if she were ever offered a guest role

Kris Jenner has no shame when it comes to being protective of her boyfriend, Corey Gamble.

During Thursday's season 4 premiere of The Kardashians, Kris, 67, revealed that she made Corey, 42, turn down a role on the western drama, Yellowstone, after learning that his storyline might include some romantic scenes.

The discussion came up in Cabo San Lucas as Kris was having dinner with Corey and her daughters, Khloé Kardashian and Kim Kardashian. "I'm so excited to watch the next episode of Yellowstone," Kris announced to the table.

Corey then poked fun at his girlfriend's interference, teasing, "If it wasn't for you, I would be a Yellowstone star."

Kim, 42, was shocked by the revelation and reiterated to Corey, "They asked you to be on Yellowstone and you said no?"

Kris then chimed in to set the record straight. "Correct, because I told him to say no," she explained.

"Why would you tell him to turn down Yellowstone?" Kim asked once again.

Owning up to her actions, Kris admitted, "Because I thought he was gonna have to have a romantic relationship."

Khloé, 39, couldn't resist joining the conversation and quipped back to her mom, "But if they said they wanted you to star and kiss with [Yellowstone star] Kevin Costner, I'm sure you would take it."

Kris didn't hesitate. "Oh, that's a hard yes!" she said.

With a laugh, Khloé joked, "Okay, so, bring on the saddle!" Corey also jokingly chimed in, "Now I know my next role!"

Kim then clarified: "Now you know your next role play! Kevin Costner."

As the foursome laughed at the table, Khloé quipped, "Saddle up, Corey!" and Kris clarified, "No, he's the best."

Costner, 68, began playing John Dutton on the Paramount Network's modern-day Western drama in 2018. His efforts on the series allowed him to earn a Screen Actors Guild Award nomination and win a 2023 Golden Globe Award. The series, which spawned an entire franchise with multiple spinoffs, is set to conclude with its fifth season in November.

As for Kris and Corey, they first connected in August 2014 while they were both in Ibiza to attend the 40th birthday party of their mutual friend, fashion designer Riccardo Tisci. They began dating shortly after, and have been together ever since.

While speaking to PEOPLE about the launch of her new personal branding MasterClass in July 2022, Kris opened up about how her longtime boyfriend has helped her along her career journey.

"I think Corey is super. He's an amazing guy," she said. "He's really supportive and he's really dialed into a lot of the different things."

"He's very knowledgeable about a lot of the things that I work on, and he really helps me in trying to think through some of the decisions I make," she explained. "He's such a great person to bounce things off of. I really love his point of view on things."

She also noted that Corey is "a people person," who thrives "helping me navigate such a huge team and all the things that are happening."

"Everybody needs somebody to sort of run something by and help make decisions about the littlest things. It could be a travel, or it could be what you're doing that evening, or it could be what's going on at the office today. But it's really great to have him," she added.
