Charlotte Keys is the firm favourite to be evicted from Big Brother 2017 tonight.
In the reality the eviction happened last night but will only be revealed in this evening's highlights show.
Charlotte faced the axe alongside Isabelle Warburton after they were put up by Hannah and Tom Barber.
Tom and Hannah appeared on the living room TV screen on Monday to the shock of the housemates, who believed they had been evicted.
Unknown to the rest of the house, Tom and Hannah only moved next door after their 'fake eviction' and had been living in secret in Big Brother's attic.
They had the power to decide which two housemates faced the final eviction of the series.
Hannah put Charlotte up for eviction, saying: "She is going to be my option of nomination. The reason being is because I feel like she should have respected the fact of how it may feel nominating another person that is a pair when you've been in that situation."
Tom then nominated Isabelle for eviction, saying: "She's nominated me twice and evicted me, so yeah I'm going to nominate Isabelle."
Lines for viewers to evict one of the pair were open for 24 hours before closing yesterday afternoon.
In tonight's show, housemates go back to school for a task during which Charlotte or Isabelle is out the back door to the shock of all the housemates.
Charlotte is the likely one to have left last night with 80% of the vote to go in our website poll.
But her potential exit will only be confirmed in tonight's show at 10PM on Channel 5.
Tonight's evictee is the first of three to leave this week with two more going out the backdoor in Thursday night's show.
The Big Brother 2017 final airs at 9PM on Friday.
