We told you earlier that Big Brother would be springing a surprise double eviction on the BB housemates tonight, well now it seems that there will be a further twist in the plot.

Throughout the day, Big Brother will provide housemates with costumes inspired by each individual housemate. Housemates must put the costumes on as they are delivered and then become that housemate until further notice.

Housemates must all refer to each other by the name of the housemate they are impersonating, they must copy their mannerisms, the way they speak and adopt their habits.

At the end of the night the two evictees will have to leave in their costumes.

A show insider told The Sun : “It’ll be hilarious – Kat could have to leave dressed as Rex.”
