Four housemates will face a double eviction on Celebrity Big Brother 2017 tonight.
However, despite just hours to go before the live show, we still don't know they'll be, with two potential groups of four up for the axe.
Earlier this week, Big Brother gathered the group to begin a murder mystery task: "Housemates there has been a murder and the victim is none other than the infamously famous celebrity agent Stella Star.
"Shortly, Big Brother will call all suspects to the Diary Room individually. At least 2 of you will be told that you are the killers. "
Sarah Harding and Sam Thompson have been voted for by the public to take part in the new twist, where they stand to gain immunity but also risk eviction.
Paul Danan and Brandi Glanville will have to uncover the killers and their success or not will determine the nominations.
As part of the task, Murderers Sarah and Sam have made four killer nominations, putting Brandi, Helen, Derek and Paul up for the axe.
Paul and Brandi then had to identify the killers. In a clip shown on Bit On The Side (above), the pair ruled out Shaun and Jemma before speculating Sam could be one of the killers.
If Paul and Brandi incorrectly identify the killers, then Sarah and Sam's four killer nominees - Paul, Brandi, Helen and Derek - will face the axe tonight.
But if they correctly finger Sarah and Sam as the culprits then Sarah and Sam face eviction, alongside two others chosen by Paul and Brandi.
The outcome of the task will only be revealed live in tonight's show.
There, host Emma Willis will open a super-fast 'flash vote' as viewers save their favourites of the four nominated housemates.
The two housemates with the fewest votes once lines close will be kicked out of the house tonight.
Tonight's Celebrity Big Brother 2017 live show airs at the earlier than usual time of 8:30PM this evening. Bit on The Side follows at 11PM.
The live final follows next Friday night from 9PM.
