It has been more than 20 years since Nicole Brown Simpson was murdered, but Kris Jenner will never forget her friend or the sense of guilt she felt about the abuse she received from O.J. Simpson.

Last night, "American Crime Story: The People v. O.J. Simpson" premiered on FX and included a scene in which the TV versions of Jenner (Selma Blair) and mutual friend Faye Resnick (Connie Britton) talked about their knowledge that Simpson frequently was abusive toward Brown Simpson, according to People. In an interview, the "Keeping Up with the Kardashians" star told the magazine she had no knowledge about how her friend suffered.

"I saw all the pictures and the police reports, and I heard the tapes of her calling 911, and that was stuff I didn't know anything about [at the time]," Jenner told People. "It's wild that she kept that from us. So I feel bad. I beat myself up because I feel like I wasn't paying attention. Like, how did I miss this?"

"They say it's very typical in an abusive relationship that the woman doesn't really speak out about how she's being treated," Jenner continued. "And that I will always feel sick about it - that she didn't really or couldn't tell any of us what was going on. I look back on some of that stuff, and I go, 'Oh, now I get it.' Some things come to my memory, and then I realize that's what was going on there."

An interview with Jenner and Caitlyn Jenner, then known as Bruce, recently popped up from the time of the trial in which Jenner told "Good Morning America's" Bill Ritter that Simpson told her "I didn't do it," according to US weekly.
