Check out the clip above to see O.J. break down inside Kim Kardashian's childhood bedroom!
In the clip, Simpson has a gun pointed to his head as he crouches in a corner of Kim's room. Robert walks in, and urges O.J. not to off himself inside his home.
"Do not kill yourself in Kimmy's bedroom," Kardashian pleads.
Lawrence Schiller, who wrote "American Tragedy: The Uncensored Story of the O.J. Simpson Defense," spoke about the intense moment during a sit-down with ABC News' 20/20 in September.
"Then O.J. said, 'I'm going to kill myself in this room,' and I said, 'You can't. This is my daughter's bedroom,'" Robert told Schiller during a recorded interview. "'My little girl Kim sleeps here. I can't have my little girl in this bedroom, and every time I come in here, I'm going to see your body lying in this. You can't do that.'"
We're definitely looking forward to seeing Cuba and the rest of the A-list cast in the 10-part mini-series when it premieres February 2.
