La Toya And Omarosa: Jackson Sister Explains 'Celebrity Apprentice' Boardroom Mistake (VIDEO)

When La Toya Jackson appeared on Donald Trump's "All-Star Celebrity Apprentice," her turn as project manager led to one of the most publicized feuds in "Celebrity Apprentice" history. When La Toya's teammate Omarosa unexpectedly left the competition to tend to a "family emergency" regarding her late fiancé Michael Clarke Duncan, La Toya's team ended up losing the challenge -- and La Toya was at risk for being fired. Back in the boardroom, Omarosa's tearful, almost defiant, explanation drew discomfort, eye rolls and palpable tension from the rest of the team. Sincere or not, everyone -- including Trump -- assumed La Toya would bring Omarosa into the boardroom with her.

She didn't.

Omarosa's crocodile tears made La Toya spare the reality-TV villain and, for that decision, Trump fired La Toya. Later that night, cameras captured La Toya's behind-the-scenes reaction for her OWN show, "Life With La Toya." In this clip, the middle Jackson sister unleashes her raw response to the entire Omarosa mistake.

"If I had to do it all over again, I would bring [Omarosa's] behind back [to the boardroom] in two seconds flat," La Toya says now.

So why didn't she at the time?

Sitting in Trump Tower with her assistant Jeffré the night of her firing, La Toya reveals why she protected Omarosa. "She started crying in the boardroom because [her fiancé, Michael Clarke Duncan] has passed," La Toya says. "And I said, 'Oh my God, Trump's not going to fire her. He won't fire her now because she missed a loved one.' I know what it's like when a loved one of yours passes."

"Oh, Toy, she was playing a game," Jeffré says gently. "She knows you have a heart and she did that purposefully."

"She's so full of it," La Toya says, shaking her head. "I just don't like this girl."

La Toya adds that Omarosa played a crucial reality-show role that Trump wouldn't want to eliminate. "I also felt that Trump would not get rid of her because she made good TV," La Toya says. "They love a villain. They love the ugliness. And that's what she was."

The season finale of "Life With La Toya" airs Saturday, June 22, at 9:30 p.m. ET on OWN.
