As part of a live task shown on Friday evening's (22 January) live show, the remaining housemates were told they would all be fighting for immunity from the next public eviction all weekend.
They will be set various tasks over the weekend to determine who is immune and who will face the public vote.
Viewers saw the first task this evening, following Megan McKenna's eviction, which involved the housemates entering a hidden musical theatre.
They had to choose a music box and then wind it up. If a gold mask popped up, then they would be immune.
Former TOWIE star Gemma won the immunity and a party thrown by Big Brother, but host Emma warned that "difficult decisions will lie ahead" for her. Oh dear...
That means Darren Day, John Partridge, Tiffany Pollard, Danniella Westbrook, Jeremy McConnell, Stephanie Davis, Christopher Maloney and Scotty T could still face eviction if they don't win immunity.
Celebrity Big Brother returns tomorrow at 10.30pm on Channel 5
