The first of this week's killer nominations have been revealed on Celebrity Big Brother 2017.
Paul Danan and Brandi Glanville are the first to be facing eviction this week - at least as things stand.
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.
In the house yesterday, 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.
"Over the next 2 days, more of you will fall victim. Housemates, these cut-throat assassins are killer nominating."
Paul and Brandi will have to uncover the killers and their success or not will determine the nominations.
"It is Detective Paul and Junior Officer Brandi's job to try and work out who these killers are," Big Brother revealed. "If they guess incorrectly, then these undercover celebrities will have got away with murder and will be granted immunity from this week's eviction, whilst those that they have killed will face the public vote.
"If however they are caught red handed, the killers themselves will face eviction."
Murderers Sarah and Sam delivered their first two of four secret killer nominations yesterday, putting Brandi and Paul up for the axe.
They'll make a further two secret killer nominations before Paul and Brandi have to decide who the killers are.
If Paul and Brandi get it wrong, then Sarah and Sam's four killer nominees will face the axe.
However if they correctly finger Sarah and Sam as the culprits they'll face eviction, although they wont be alone.
