'Get in the Ring' involves housemates battling it out against each other inside a wrestling ring set up in the garden.
Aaron Allard-Morgan will act as the referee, and will pick each of the bout pairings. He will also decide who the deserving winner of each round is.
The other housemates will be able to pick their own wrestling outfits and styles from a costume box provided by Big Brother. They will each have to choose a special alter ego and wrestling name to be introduced as when they walk into the ring.
In each fight, the wrestlers must kneel down on all fours, facing each other. They must try to grab both socks off of their opponent. The wrestler who takes off both socks first will win the bout.
The three winning housemates will then be awarded with a special prize later.
The housemates were earlier set a food-themed Cinnamon Challenge task.
