Yesterday, housemates took part in a talent show performance, which both the Queen and King of the Fairies - Cami Li and Perez Hilton - judged.
Big Brother asked Cami and Perez to choose two housemates who impressed them the most, and Nadia and Keith were triumphant.
Nadia and Keith were told that winning the task meant they would now be court jesters, but it wasn't until later that Big Brother explained they have been given an "additional reward" - immunity from eviction.
While Keith appeared pretty chuffed, Nadia seemed a little disappointed, saying: "Oh, that's a punishment. I can't believe it, bloody immunity."
Any remaining housemates who are not saved by the King and Queen will end up facing Friday's first eviction.
Cami was named Queen of the Fairies during Tuesday night's live show as part of a twist introduced by Big Brother after the first eviction was cancelled.
Housemates had to nominate which other housemates to save and who to put up for eviction, unaware that the person put up for eviction would actually be immune, and would be given powers for two days.
As Queen, Cami later chose gossip blogger Perez as her King, which subsequently gave him immunity.
