Keeping Up With The Kardashians matriarch Kris Jenner has admitted that cheating on her ex-husband, Robert Kardashian is "the biggest regret of [her] life".
The reality momager was marriage to the lawyer for 12 years after finding love as a teenager, and they had Kourtney, Kim, Khloe and Rob together but the 56-year-old later went on to cheat on him with a producer called Ryan.
Her affair is documented in her memoir Kris Jenner... And All Things Kardashian, but on The Tonight Show With Jay Leno, she said: "He was the only guy that I had dated. When you're very young you do a lot of stupid things. and it's probably the biggest regret of my life that I ended up having an affair."
Talking about her attitude to marriage Jenner, who is now married to Bruce, added: "[I was] probably just really naive and stupid and restless and didn't realise that marriage has its ups and downs. Someone once told me that it's like a roller-coaster, just ride it out, but I wasn't really old enough to hear those words."
In the book Jenner claimed that she "had wild sex everywhere, all the time", with the producer before the pair got caught.
Robert Kardashian, who represented O.J. Simpson during his infamous trial, died in 2003 from esophageal cancer.
