Of course, Simpson's connection to the long-running E! Network series doesn't just come from a natural curiosity about the Calabasas Clan or a love for Scott Disick's latest antics. The family's rise to fame will always be linked to Simpson's name and the controversy surrounding his 1995 trial for the murder of his wife Nicole Brown Simpson.
As any fan of last year's acclaimed American Crime Story: The People Vs. O.J. Simpson knows, the former football star was close friends with Robert Kardashian -- the father of Kim, Kourtney, Khloé, and Rob -- and recruited him as part of his legal defense team. In the series, he was played in all his "Juice!" glory by Friends star David Schwimmer.
The Emmy-winning show -- which came out the same year as Ezra Edelman's Oscar-winning documentary, O.J.: Made in America -- explored the relationship between Simpson and the Kardashian family. Kris Jenner, who was friends with the murdered Nicole Brown Simpson, was portrayed by Selma Blair. (The article notes that Simpson couldn't watch People Vs. O.J. because the prison didn't get FX.)
