Will Smith broke down in tears during his reunion with his Fresh Prince of Bel-Air co-star Janet Hubet as she opened up about the "mistreatment" that took place on set.
The 52-year-old actor joined Janet, 64, for an emotional conversation during Friday's special episode of Facebook Watch series Red Table Talk.
Will and Janet buried their 27-year long feud after they came together with the rest of the cast to celebrate the sitcom's 30th anniversary recently.
Disucssing Will's behaviour while filming the US sitcom three decades ago, Janet said: "He was young, he was out of control in his own way, he had all this power.
"There was a need for me to have professionalism on the set because I was used to it, especially as a dancer."
Admitting to his rude behaviour, Will said: "I wasn't perceptive and, ultimately, I wasn't kind."
Janet, who starred on the first three seasons of Fresh Prince as the original Aunt Viv, continued: "I would sit in my car some nights and not want to go anywhere.
"I didn't want to go home, I didn't want to go to work.
"The misconception of me was that I was haughty, difficult, wanted to be the star of the show."
Father of two Will added that the tension between the pair was behind the decision to "reduce her role."
The actress said: "As the oldest woman on that set, there's that respect level that I just needed to have of being an older woman, a black woman.
"I had been banished and they said it was you who banished me, because I didn't laugh at your jokes.
"Then they ordered me to stay in my room, I couldn't come out on the stage. And I wasn't unprofessional on the set, I just stopped talking to everybody."
Janet was later offered a "messed up" deal that would allow her to work for two months and two weeks without taking on other jobs during that time.
Will said he wasn't aware of the details of the negotiation, though said he understood why she didn't agree to it.
As Will began to cry, Janet continued: "But you're the big star, I'm just a little Black b***h."
The two then decided to take a break from the emotional conversation.
Will returned to speak to clinical psychologist Dr. Ramani Durvasula about his behavior on set, admitting he acted like a "scared little boy" that "didn't realize the power" of his words.
The famous actor acknowledged his part in the feud and said "it was all way too far on my end."
Prior to the ending their feud, Will and Janet were known to publicly slam each other throughout the years.
