Big Brother on Thursday night introduced a brand-new challenge that forbids communication between the male and female housemates in a shocking turn of events.

Until Biggie says otherwise, housemates of the opposite sex are not permitted to communicate with one another.

According to the twist, men will only be able to communicate with other men and women with other women.

The guys and the girls have been split into two tribes that can only speak through a mediator nominated by each gender, Yaya and Miracle.

The mediator can only speak a certain number of times per day in squared-off areas for a time period to be decided by Biggie.

The twist also required that the housemates change sleeping arrangements: females in one room (Alex), and males in a different room (Sandton).

No female must cook for the male housemates again, and vice versa. They are not allowed to use the kitchen at the same time.

Also, they must be separated during the use of the arena and party room.

The housemates were subjected to the new twist from Biggie after the successful wager task presentation and after Nelisa, Blue Aiva, and Olivia broke one of Biggie’s rules by engaging in a physical fight.
