Before we see them make their debut in tomorrow’s (21 June) show, get to know Isabelle, Sam and Savannah a little better below…

Channel 5
Age: 21
Job: Unemployed
In a nutshell: Isabelle describes herself as being “funemployed” and living off her father’s money, remarking “I want to have the best summer ever. I’m in-between jobs at the moment so why the hell not!”
She’s also going to be a blast from the past for one housemate in particular, having hooked up with Kieran Lee in Ibiza last year... which we’re sure Rebecca is just going to be thrilled about.
Sam Chaloner

Channel 5
Age: 24
Job: Construction worker
In a nutshell: Self-professed “ultimate lad” Sam says his biggest passion is “pulling birds”, and has an eye for older woman, claiming he once got together with his mum’s friend at a hen do.
Sam also once appeared in ‘Ibiza Weekender’, so we’ll have to wait and see whether former holiday rep Ellie Young clocks him from his past stay.
Savannah O’Reilly

After winning 'Big Brother 11', Josie was quickly thrown back into the house when 'Ultimate Big Brother' started, but walked after a few days declaring "I'm not a celebrity I'm just normal".We suppose it was sharing a house with A-listers like Preston from the Ordinary Boys and Makosi that intimidated her so much.

The people's favourite, Brian triumphed over Nadia, Makosi, Josie and - bizarrely - Ulrika Jonsson to be crowned 'Ultimate Housemate'. (credit:Yui Mok/PA Archive)

While the returning Nikki Grahame was obviously the star of the series, she wasn't eligible to win (sadly). Instead, the 'Timebomb'-themed run was won by normal lass Chloe. (credit:Ian West/PA Archive)
