Kris Jenner has opened up about being unfaithful after she was grilled by her daughter on the latest episode of The Kardashians.
Speaking to Khloe Kardashian on Thursday's episode of their popular reality TV show, the mom-ager got real about her relationship with her ex, Robert Kardashian Sr.
The pair were married for 12 years until their divorce in 1991 and had four children: daughters Kourtney (born 1979), Kim (born 1980), Khloe (born 1984), and son Rob (born 1987).
When questioned about why she had cheated on someone she loved, Kris credited the mistake to her mindset at the time.

"I think being really young and dumb is something that plays into it because you don't really understand the consequences of your actions," she said during the October 26 episode.
As for the exact reason behind her infidelity? The 67-year-old 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," she 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 the pair seemingly kept up a close relationship, even after their divorce up until Robert's 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?'"
Have a look at the segment below:And while Kris stated that she may have her regrets about her rocky past, she believes everything worked out as 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 her daughter. "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."

The news comes after the mom-of-six got candid about what she hopes for Khloe after the multiple cheating scandals she was forced to endure at the hands of her ex, Tristan Thompson.
"I just want Khloe to be really careful when she makes these decisions and she has to let somebody go." Kris said.
Khloe and Tristan share two children, True, 5, and Tatum, 1, who they co-parent amicably.
Speaking to Hollywood Life last year, an insider told the publication that despite being hurt multiple times by the basketball star, Khloe is committed to doing what is best for her children.
"Khloe still wants Tristan there for the special moments, she feels it’s important for her kids to have those memories with him and bond," the source said. "She’s aware that people are going to have opinions about her inviting him around but she’s not going to let that stop her from doing what’s best for her kids."

They also stated that "it wasn't easy for her" but she put her own feelings aside to allow her children to spend time with their father.
"It actually took a lot of strength for her to be able to put aside her own anger and pain and allow for him to be there for Halloween with the kids," the insider continued. "It certainly isn’t easy for her, but she’s doing it because him having a bond with their children is more important to her than letting her own feelings run the show. Does it make it easy for her? No.
"But she doesn’t care because the happiness of her children comes above all else," they concluded.
