Big Brother has dropped an Annihilation bombshell on the house today.
The coming week is being touted as the show's biggest twist in its HISTORY.
"Big Brother is about to tear the house apart," Emma Willis teased in Friday evening's live show. "From Monday, friendships will be put to the test as housemates are forced to make some tough decisions."
Today Big Brother gathered the housemates in the house and told them: "Big Brother has some important news.
"Housemates, your time in the Big Brother house is about to change forever.
"Today, an unprecedented annihilation begins putting each and every one of you at risk of eviction."
All of the housemates' status on the screens in the living area then changed to nominated as Big Brother continued: "Housemate numbers will be decimated but here are no public votes, who survives is down to you.
"Over the coming days, Big Brother will set a number of tasks that you will all take part in.
"All will end with the most serious consequence of all for one person. Whoever survives will be a significant step closer to being the winner of Big Brother.
"You are now all bidding for your own survival, who will you choose to annihilate? Big Brother will get back to you."
This week the public won't have a say as the housemates themselves decide which of them will be going home.
Those unlucky enough to be picked will be given the boot right there and then.
They won't have time to glam up or do their make up, but that doesn't really matter as they won't be walking down the cat walk or having their photos taken anyway.
Instead, they'll exit via the back door before appearing with Rylan Clark-Neal on Bit On The Side.
Big Brother airs nightly on Channel 5.
