Kris Jenner is portrayed in 'The People v O.J. Simpson' as someone who fiercely believes O.J. murdered Nicole Brown Simpson and is angry that ex-husband Robert Kardashian is defending him ... and we know the sentiment is real.
The promo for next week's show has a scene where Kris angrily confronts Robert. Our sources -- definitely in a position to know -- say Kris did indeed have angry exchanges with her ex and believed strongly from the minute she found out Nicole was murdered that O.J. did it.
Kris was very close to Nicole and knew O.J. well. She and a group of friends who were close to Nicole all shared the same sentiment.
As for the specific confrontation in the promo where Kris faced off with Robert, who initially believed his friend was innocent ... it really did happen.
