Four housemates had been up for eviction tonight - Katie H, Alicia Douvall, Perez Hilton and Nadia Sawalha - but unknown to them, Big Brother had actually CANCELLED the live eviction because of Alexander O'Neal's departure.
Instead, the stunned housemates were told by Emma Willis that there would be a major twist...
In scenes aired tonight, we discovered Katie P had been called to the Diary Room yesterday and told she must save the most entertaining housemate from eviction and nominate the person she feels is the most boring.
She had 24 hours to think about her decision.
On tonight's live show, Katie P was again called to the Diary Room and the other housemates watched as she chose to save Katie P and nominate Calum.
Katie P said beforehand: "You know I have to do what I have to do, I love you all."
Her reason for nominating Calum wasn't so much that he was boring, more that she didn't think he had a chance of being voted out by the public.
Calum took his nomination well, simply saying: "I'll take it."
So now, Calum faces eviction on Friday night's live show alongside Alicia Douvall, Nadia Sawalha and Perez Hilton. Voting lines open during tonight's Big Brother's Bit On The Side.
Meanwhile, Calum and Alicia settled their differences today after Alicia admitted her annoyance at Calum nominating her at the weekend.
Alicia branded Calum "two faced" when she discovered he'd nominated her, while he insisted he'd only done it because he hadn't bonded with her as much as other housemates.
Today, they patched up their differences... but not before Big Brother punished them - and the house - for breaking rules discussing nominations.
Housemates were told they couldn't use the hairdryers or straighteners until further notice.
