The 'Yes!' task requires the housemates to reply in the affirmative to all Big Brother's questions. If they succeed and complete their challenges, they will win a luxury shopping budget.
Today's challenges will include being asked by Big Brother if they want to watch back Monday's nominations as a group. Rebeckah Vaughan and Heaven Africa were nominated and face eviction on Friday.

Meanwhile, Faye Palmer will have a tattoo prank played on her as Big Brother will ask if she wants the word 'Yes' tattooed on her arm. Just before the needle makes contact with her skin, a rubber stamp will come out and press a removable 'yes' on her instead.
Earlier today, Tom O'Connell became the second housemate to fail on a 'Yes!' task, refusing to have a short-back-and-sides haircut. Yesterday, Harry Blake refused to pose in his pants for a Gay Times photoshoot.
Later today, Heaven will be asked by Big Brother is she wants to do a bungee jump. If she refuses, another housemate will be asked to take her place.
