There was no public vote for a Bushtucker challenge yesterday, with hosts Ant and Dec joining camp to make a surprise announcement.
"We have news," the pair told to the group. "Today the public have not been voting for one of you to take part in a trial. That's because today is the start of a brand new challenge called Claim of Thrones."
Ant and Dec explained that all 12 of the current celebrities will be taking part in a new challenge.
In this preview clip, we see the group of 12 split in half to each take on a trial called 'Vicious circle'.
Placed in critter coffins, each celeb is joined by snakes on their head, cockroaches over their bodies and a surprise at their feet.
"They're biting my boobs!" yells Ola after rangers dump a total of 3,000 insects onto her chest.
"Mine too!" quip Danny Baker, while Ant and Dec give a cheeky look to camera.
Four of the celebs will emerge victorious from the challenge tonight and Claim A Throne in Snake Rock camp.
They'll enjoy luxuries including hot showers, food and pampering sessions as they live like royalty.
The other celebs will become their subjects and will have to live off basic rations.
But that's not all.
"At the end of the task, the four reigning will be immune from first public vote off," Ant and Dec teased.
The results of the trial will air tonight (Wednesday) on ITV at 9PM.
I'm A Celebrity Get Me Out Of Here airs nightly on ITV.
