Here are all the pictures from tonight's Big Brother 2017 highlights.
In this evening's episode, there's a shock eviction before those that remain celebrate making the final - or so they think.
After waking up, housemates are told that Big Brother will be taking them through the stages of life in fast forward. First up, Tom and Isabelle are taken back to early childhood with an adult-sized play area. They must use alphabet blocks to answer questions given by Big Brother, whilst dressed in adult-sized baby grows .
For the second part of the day’s task, Big Brother is sending housemates back to school. Housemates are dressed in school uniforms, sat behind desks
Big Brother then grades the housemates on their dress sense, based on the result of a public poll. Isabelle and Charlotte came first
The second subject of the task is power. Hannah and Kieran come first in the public poll.
During the task and revealed in tonight’s show - Charlotte or Isabelle was evicted and exited out the back door which shocked all housemates
Later, Big Brother throws the housemates a Graduation Ball, and announces that the final vote to win is now open to the public.
“I’m buzzing!” says Hannah as the group celebrate making the final.
However there's an unfortunate revelation when Raph is in the diary room talking to Big Brother about reaching the final week, not the final itself.
He had thought he was a definite finalist but Big Brother clarifies they have not made the final. Unknown to housemates, two will be evicted out the backdoor on Thursday.
Elsewhere tonight, an argument over pranks leads to Raph and Andrew locking horns.
Big Brother 2017 airs tonight at 10PM on Channel 5.
