The two Celebrity Big Brother housemates with the fewest votes will face a game of chance to determine their place in the show during Friday night's live eviction.
Chloe Khan, Marnie Simpson, James Whale and Stephen Bear are at the public's mercy as they face the boot from the programme.
X Factor reject Chloe joined the list of nominees at the last minute, taking Renee Graziano's place on Thursday.
The Mob Wives star had been up for eviction but secured a "save and replace" during the shopping task - and picked Chloe instead.
Earlier, Marnie, James and Renee had been chosen to face the public vote during so-called "killer nominations", delivered face-to-face in Wednesday night's episode.
Bear will face the public vote every week because he has an eternal nomination.
In footage that will air on Friday night, housemate Aubrey O'Day will be punished for discussing nominations, prompting Marnie and Chloe to ask why Aubrey wanted to see them up for the axe.
This leads to a row with Renee, which housemate James compares to something you see "outside a pub on a Saturday night".
The contestants also continue with Big Brother's Big Risk task, choosing whether to play for their own benefit or for the good of the house.
Frankie Grande, Renee, Bear, Chloe, Heavy D and Marnie choose to play for themselves, while Katie Waissel, Samantha Fox, Lewis Bloor, Ricky Norwood and Aubrey play for the house.
Celebrity Big Brother is on Channel 5 at 9pm.
