One housemate left the Big Brother 2017 house last night, it's been confirmed.
However their exit will be kept secret - at least if everything goes to plan - until Friday evening.
They're all in danger following a week-long nominations twist called 'The Hunt'.
In 'The Hunt', housemates had to avoid losing series of games to keep themselves safe from eviction.
One by one, housemates were targeted for eviction and at the end of it all, Sue, Isabelle, Chanelle and Simone were the ones in the danger zone.
Lines for viewers to vote to evict one of the four opened just on Wednesday but closed last night (Thursday) during Big Brother's Bit On The Side.
The housemate with the most votes to be evicted at time the lines closed will be kicked out in the middle of the night via the 'backdoor'.
It's not yet been revealed exactly how they'll make their exit but Bit On The Side host Rylan Clark-Neal teased: "They will literally disappear from the house!"
Their exit will be kept secret until its revealed during Friday's highlights.
Then the evening's live show will see the next two housemates with the most votes to be evicted put up for another vote - this time from their fellow housemates.
The safe housemates will decide which of the pair also leaves the house, with the unlucky housemate leaving via the front door this time.
And in one final twist, host Emma Willis will enter the house to host the vote from the inside.
Both of the two evicted housemates will then chat to host Emma about their time in the house.
