Kim Kardashian inherited more than just good genes and whip-smart business sense from her mom Kris Jenner. Mama J also hasn’t had the best luck keeping things together after saying “I Do.”

On Jay Leno Wednesday night, the reality empire matriarch opened up about the affair that ruined her marriage to Robert Kardashian, Sr. (a.k.a. the father of all her children save for Kendall and Kylie). Mama J – who wrote about the affair in her book in detail – called it “the biggest regret” of her life, adding that she was “really naive...stupid and restless” at the time.

(In her defense, Mama Jenner met Robert Kardashian at the wee age of 18, and he was the first man the future powerhouse ever dated.) Despite the devastating effects, deets of Kris’ tryst with the producer are pretty interesting. In her book, Mama J writes that she and her lover, Ryan, had “wild sex, everywhere, all the time.”
