As a friend to victim Nicole Brown Simpson and the ex-wife of O.J. Simpson's attorney, Robert Kardashian, Kris had an intimate look at the infamous murder trial that is now the subject of a FX miniseries.
Just three months before Nicole was murdered in June 1994, Kris and her children, Kourtney, Khloe, Kim and Rob, went on Easter vacation with Nicole and her children, Justin and Sydney.
"That was such a fun trip," Kris told ET. "Nicole was in charge of music because she was so good at her playlists. I remember we watched Pretty Woman probably 10 times on that trip. It was our last vacation together."
Despite how close she was to the trial, Kris told ET that no one from The People v. O.J. Simpsonfact-checked with her on the details.
"In one of the scenes, they show my kids sitting in front of a TV, watching the reading of what they thought was a suicide letter from O.J.," Kris said, explaining a scene in which the kids are seen clapping and chanting their last name while watching their father on television. "We were hanging out at my house and this didn't happen."
Selma Blair plays Kris in the series, and the 60-year-old momager says another thing they got wrong is her appearance.
"I was pregnant with Kendall when we were going through the trial, and she's 20, so there you go," Kris said.
In a promotional tease for next week's episode, viewers saw Selma (as Kris) upset with David Schwimmer (as Robert) for defending O.J. Kris admitted that this part wasn't that far off.
