It will be part of a double eviction twist that will see two housemates out by the end of Friday night's show.
As was previously confirmed by host Emma Willis last week, this week will see a two housemates leaving but it won't be straight forward.
One shock eviction will happen in the house on Thursday via the backdoor, with the result to be revealed in Friday night's show.
Then live on Friday, Emma will enter the Big Brother house for the second eviction of the week!
Both evicted housemates will be interviewed live by Emma from the eviction studio on Friday evening.
It's not yet been announced precisely how the double eviction will work, with nominations yet to take place.
There has been some speculation that we could see one 'original' housemate and one 'second chance housemate' go.
Four new-ish housemates joined the house at the end of last month, halfway through the series.
Andrew Cruickshanks, Simone Reed and Sue Evans were originally at the launch night where they faced a public vote to enter the house, but lost out to Tom who went on to become the People's Housemate.
The trio are joined by Sam Chaloner, who wasn't chosen to join the house by the current housemates last week in a twist. Instead they decided to pick Savannah and Isabelle.
The four piece entered the house as 'second chance housemates' where it was revealed they can NOT win Big Brother or the main prize.
However they have stolen £15,000 from the prize fund which will be given to the 'second chance housemate' who lasts the longest in the house.
Big Brother continues nightly on Channel 5.
The double eviction airs next Friday from 10PM.
