Kim recently shared that she had an emotional moment remembering her father when she last saw O.J. Simpson, a client and friend of her late father.

Robertserved as a defense attorneyfor during Simpson’s 1994 murder trial for the violent deaths ofex-wife Nicole Brown and her friend Ron Goldman.

The reality star explained to close friendJonathan Chebanon his new podcast,FoodGod: OMFG,that the last time she saw Simpson she thinks was in Miami.

“It was before he had gone to jail last situation, and Khloé and, I think me Kourtney and Khloé were in Miami in a club, and we ran into him in the VIP section. But it was like behind a stage or something, I don’t even know what club it was at. We all, I think, started crying. It was emotional, I think,” said Kim.

The murder trial has since been widely publicized on television, including in FX’s award-winning series,American Crime Story: The People vs. O.J. Simpson.

“I just watched the whole O.J., I missed the whole thing, and I just watched it, and I can’t believe your dad was such a big part of it, it was crazy,” said Cheban. “I never met your dad and for me to see that, and my connection to you, like I watched the O.J. trial, and I can’t believe I didn’t meet him. Because of him, and there’s you, and then there’s like me, and it’s like a weird…”

“You guys would have gotten along so well,” Kim said of her father.

Cheban pointed out that despite their longtime friendship, he and Kim have never spoken about her father’s involvement in the trial.

“Yeah, we never really talk about it,” she said. “I never really talk about it.”
