The US reality star previously asked to leave the house last week, before changing her mind.
Last night, she broke down in tears and reaffirmed her desire to exit the show.
She told Ashley James: "I don't live a competitive life at all. I don't fight and bitch and moan and try to pick out the horrible things about people all day.
"It sucks for that to be a practice in my life. That makes me be someone that I'm not. And that's truly uncomfortable. I'm bored with this. I don't want to do this kind of s**t any more."

Malika continued: "My life is better than this. It's full of love and acceptance and like camaraderie and it's not saying that I don't have that here but it's like, I don't care to fight.
"I don't care to tell someone what I think about them So what, that's your problem. In my life I don't deal like that. I've grown very tired of the structure of this.
"'Why do you think I should win?' I don't think I should win. 'Why should you be in the final?' I don't think I should be in the final."
Malika then concluded: "I've done the best that I could thus far. Kicking, screaming crying, I've done all that I can."
Discussing tonight's impending eviction, where Malika faces the axe, she added: "I can't wait."
