Kris Jenner Shares Why She Cheated on Robert Kardashian

Kris Jenner is baring it all.

The Kardashians star—who was married to ex Robert Kardashian, Sr. for 12 years until their 1991 divorce—is opening up about why she was unfaithful to the late attorney. After daughter Khloe Kardashian asked her mom why she cheated in her past relationship during the latest episode of The Kardashians, Kris chalks up her decision to the mindset she had in her early 20s.

"I think being really young and dumb is something that plays into it," Kris—who also shares kids Kourtney Kardashian, Kim Kardashian, and Rob Kardashian with Robert—said during the Oct. 26 episode, "because you don't really understand the consequences of your actions."

As for the exact reason she thinks she stepped outside of her relationship? Kris admitted that all these years later she's still not sure if she has a concrete answer.

"I don't know, because he was such a great husband and such a great dad," the mom of six explained to Khloe. "And I think that I fell into a situation where I thought that the grass was greener somewhere else and I made a huge mistake. That's like my life's biggest regret."

But despite their split, Kris noted that she and Robert remained as close as ever until his death in 2003 from esophageal cancer.

"We talked on the phone all day long, helped each other through things all the time," she says in a confessional. "And I did have regrets. I thought, 'Wow, what I was thinking?'"

For Kris, her perspective comes amid watching Khloe navigate her co-parenting relationship with her ex Tristan Thompson, with whom she shares kids True, 5, and Tatum, 14 months. Despite the former couple's public split in 2021 after the NBA player's multiple cheating scandals, the matriarch noted she wants to her daughter to be certain that she's ready to move on.

"I just want Khloe to be really careful when she makes these decisions," Kris shared, "and she has to let somebody go."

And while Kris—who is also mom to kids Kendall Jenner and Kylie Jenner with ex Caitlyn Jenner—may have her regrets about the past, she believes her life played out exactly how it was meant to.

"You know, I'm not proud of the way that I behaved during that time, but you know what?" she told Khloe. "Everything happens for a reason. I really do live my life by thinking God has a plan. And without that whole thing happening, there never would've been Kendall and Kylie."

Why, yes, Kris Jenner and longtime love Corey Gamble are still doing amazing, sweetie. Nearly nine years ago, the music industry insider approached the world's most famous momager at fashion designer Riccardo Tisci's 40th birthday bash in Ibiza and "I just tried saying, 'You're beautiful. I'd love to get to know you,'" he shared on the family's OG series, Keeping Up With the Kardashians, "and it went from there."

A decade on, Kris is still loving life with her "walking, talking Luther Vandross song." Marking his 42nd birthday last November, the 67-year-old thanked him "for bringing so much love and light into my life. You are so smart, kind, generous, funny, protective, and creative. You remind me every day how blessed and lucky we are."

With all due respect for all the small things, Kourtney Kardashian's husband has made some pretty grand gestures throughout their yearlong marriage. Take her 44th birthday this past April that saw her and Travis Barker take a trip up the California coast to Santa Barbara. The Blink-182 drummer, 47, marked the occasion by filling their room at the famed Kennedy Cottage with rose petals and gifting her with a $161,819 piece by artist Yoshitomo Nara. 

In turn, Poosh founder, pregnant with their first child together, has fully embraced her new life as the girl at the rock show. "One year," she wrote on Instagram marking their first anniversary May 15, "forever to go." 

As Kim Kardashian put it in a trailer of The Kardashians, "Things change really quickly." When season two wrapped, the 42-year-old was still living it up with then-Saturday Night Live standout Pete Davidson.

Then, over the summer, she got fans hoping she was getting back in the dating game with retired NFL quarterback Tom Brady. 

Alas, the mom to North West, Saint West, Chicago West and Psalm West—with ex-husband Kanye West—wasn't on the hunt for a new teammate. "They have friends and business partners in common, but [are] not dating," a source told E! News. "Kim is very focused on her kids, her businesses, law school and preparing for American Horror Story."

As for those rumors she's dating Odell Beckham Jr.? Well, as a source told E! in September, "She's not seriously dating anyone at the moment but open to finding love again if she meets the right person."

In an episode last season, Kris shoots her shot while chatting with Khloe Kardashian about Tristan Thompson, asking, "How's everything going with Tristan?" Safe to say the Good American founder, 39, has the L.A. Lakers power forward benched for now. Though the exes have worked out a game plan for raising daughter True, 5, and son Tatum, 13 months, Khloe recently shot down the idea that they're back together, calling the narrative "tiring."

She's more interested in starting a fresh story. After meeting Love Is Blind star Alexa Lemieux in April, Khloe pitched a winning idea to Netflix, writing on Instagram, "I think some of us single K sisters should go on LIB. What do you think?"

Months after Kendall Jenner's split with NBA guard Devin Booker last fall, the model's love life got an assist from friends Justin Bieber and Hailey Bieber. The married duo were spotted enjoying a double date with the reality star, 27, and musician Bad Bunny, 29, in February. Several months, one tropical vacation and several coordinated fashion moments later, the new pair is still collaborating. 

Seems Kylie Jenner has found herself a new beautiful boy. Last seen publicly with rapper Travis Scott—dad to her daughter Stormi, 5, and son Aire, 15 months—at an Art Basel party in December, the beauty mogul, 25, has been linked to Oscar-nominated actor Timothée Chalamet, 27, since April. Now, rise and shine because you don't want to miss the glimpses they've given us of their romance at New York Fashion Week and the US Open.
