Ann Widdecombe, Jess Impiazzi, Wayne Sleep, Shane Lynch and Shane Jenek will compete to be crowned winner of Celebrity Big Brother in the live final of the reality show.
The series will come to an end just over a month after the first contestants entered the compound.
The show began on January 1 with an all-female line-up to celebrate the year of the woman, with a cast of male celebrities joining them on January 5.
Transgender newsreader India Willoughby was the first housemate to be evicted, followed by journalist Rachel Johnson.
The eliminated housemates were reunited with the rest of the inhabitants of the house in Thursday’s episode of the show.
Johnson entered first to perform a rap before all the eliminated reality stars, including Andrew Brady, Willoughby and Amanda Barrie, made a surprise appearance.
The episode started with former housemate Ginuwine taking a seat in Big Brother’s chair and playing his hit Pony into the house.

A group of male strippers then entered and proceeded to gyrate for the audience.
Widdecombe was horrified and covered her ears with her hands before rushing to the bedroom to put a towel over her head.
There was an emotional reunion between Brady and Jenek, also known as drag queen Courtney Act, as the former Apprentice candidate backed his friend to win.
