Kris Jenner, who was married to ex Robert Kardashian, Sr. for 12 years until their 1991 divorce stated the real reason for being unfaithful to the late attorney.
During the latest episode of The Kardashians aired on October 26, Kris commented: "I think being really young and dumb is something that plays into it because you don't really understand the consequences of your actions."
The question was asked by her daughter Khloe Kardashian why she cheated in her past relationship.
"I don't know, because he was such a great husband and such a great dad. 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."
