Christopher Biggins and Storage Hunters UK's Heavy D became the final stars immune from eviction on Celebrity Big Brother as the show's twist was revealed.
Pantomime star Christopher, who is currently the "Secret Boss" of the house, was asked to serenade the housemate he wanted to nominate for eviction with Tina Turner's Simply The Best.
He belted the tune out to TV personality Heavy D, who, in a twist known to the housemates and not Christopher, actually gained immunity from Friday's live eviction.
In the Diary Room, Heavy D, whose real name is Colin Newell, expressed his delight at Christopher's decision.
He said: "Immunity, boom! Wicked, lovely. Now I can chill, thank you. Get in there immunity."
It meant that Heavy D and his catchphrase will survive for another week, which wasn't the best news for everyone.
Christopher was then called into the Diary Room and told that he had actually been saving his fellow housemates, which he took in good humour.
"You bastards! That's very, very funny.Very, very clever," he laughed.
He was then told that he had made himself immune by successfully completing the task.
Outside the Diary Room, he was greeted by his jeering housemates.
"I tell you, it's been a f****** nightmare," he told them, smiling.
The pair join Loose Women panellist Saira Khan and The Only Way Is Essex's Lewis Bloor in being safe from eviction.
