The bombshell was dropped on the housemates moments after they had nominated each other for eviction in the diary room.
Afterwards, Big Brother informed the contestants that their nominations were a fruitless venture.
He attributed his decision to nominate almost all of them to their repeated failure to adhere to the rules of the house.
Since the housemates are in pairs, two of them may possibly be evicted at the weekend during the live show.
Khloe became the new head of the house after trumping Ifu Ennada and Bambam to win a contest.
After her emergence, Khloe told her fellow housemates, “Guys please help me; I am a woman of many flaws”.
Tobi Bakare was the head of house for the first two weeks of the reality television show which is in its third season.
