“One of my biggest regrets in my life is that our marriage fell apart,” the 62-year-old said.
It was Kris’ “affair with a soccer player” (Emmy-nominated animator, Todd Waterman) which truly led to the couple’s divorce.
“It’s nothing I’m proud of,” Kris admitted.
Kris and Robert married in 1978 when Kris was just 22 years old.
“I had the happiest life you could’ve dreamt about. But when you’re in something, sometimes people think the grass is always greener and that was like what I think I went through at some point,” Kris told Levin.
Robert and Kris, who share children Kourtney, Kim, Khloe and Rob, legally divorced in 1991.
