Big Brother has revealed a new set of twists for the week ahead.
It follows new housemates Hussain Ahmed and Isabella Farnese joining Big Brother in the latest live show.
They made their entrance in Friday's episode, following the latest eviction which saw Isaac Jagroop eliminated.
Host Emma Willis announced that the pair will be immune from this week's latest nominations.
But they will be taking part in a secret task over the weekend that will see one of them able to bank a load of Big Coin.
Ahead of entering the house, Isabella said: "At the moment the Housemates know they are on a gameshow – they all want to win. I think I will forget about the cameras, even to the point where it might be too much and think ‘Rein it in!’
"I am going to be me and hope the public like me. I hope I come across how I am seen on the outside world with friends. The people you would least expect me to get on with, I get on with. My best friend does not wear make-up, she is like a country girl. I want to surprise people."
Hussain added: "I want to show myself and all the swag and sauce that I’ve got, and secondly to win that £100,000. I have a plan on how I am going to win it, but knowing me the plan always goes out the window because I can’t keep my mouth shut and I have to be myself all the time, which is sometimes a problem."
Meanwhile, there's also the chance for one of the current housemates to achieve immunity.
Big Brother's weekly auction will see housemates able to bid for immunity using their Big Coins. Currently Tomasz Wania is the richest housemate after Isaac donated his Big Coin total to him after the eviction.
Big Brother 2018 continues Sunday-Friday nights at 10PM on Channel 5.
