This is because following Gillian McKeith's entrance into the house, where she picked four housemates to be cleansed by going into her toxic clinic, she had the chance to swap some housemates for others.
Stephanie Davis, John, Tiffany Pollard and Scotty were the original four chosen, but following her reassessment, Gillian chose to keep Steph and Tiffany in the toxic room, but announced that Darren Day and Jeremy McConnell would be joining them.
That also meant that Steph, John, Tiffany and Scott lost their right to vote.
The pure housemates were then instructed by Big Brother that they will nominate in the Diary Room. This will be shown on tonight's show.
Which housemates will be up as the series approaches its final week?
CBB airs at 9pm on Channel 5.
