Kris Jenner
In 2011, Kris Jenner admitted to cheating on her late husband, Robert Kardashian, with a producer whom she had “wild sex everywhere with.” “He was the only guy that I had dated [Robert Kardashian]. 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,” said Jenner. Jenner’s affair spurred rumors that her daughter Khloe isn’t a “real” Kardashian.
