Jamie Lomas and Rebekah Vardy are sent 'Grotholing' in the next I'm A Celebrity 2017 Bushtucker Trial.
Meanwhile, show bosses have confirmed that the first elimination will take place tonight.
Yesterday marked viewers' last chance to decide which celebs would face their fears in one of the ITV show's scary challenges.
Amir Khan, Dennis Wise, Georgia 'Toff' Toffolo and Vanessa White were ineligible to be chosen as they are currently members of the secret 'Fright Club'.
Hosts Ant and Dec addressed the other seven campmates yesterday evening, announcing that Becky and Jamie had topped the latest poll.
The duo will now have to go 'Grotholing' to earn meals for their comrades in Croc Creek.
They will be shut in a dark cave for the task, encountering spiders, rats and other jungle creatures. However, one will be blindfolded, making the search for stars that extra bit harder.
"Two celebrities crawling through matching tunnels of torment, but only one can see," a teaser said.
"Communication is the name of the game when you're Grotholing."
With the Trial votes done for the series, viewers will now have their say on which celebs they want to keep in camp.
Ant and Dec announced that the first elimination will take place in tomorrow's episode.
Currently, the Fright Club members are completing secret missions to win immunity for some of the campmates.
In yesterday's Bushtucker Trial, Amir and Toff won eight meals for Croc Creek and the first 'immunity key' after downing disgusting drinks.
Dennis and Vanessa then secured another key in a late-night 'chamber challenge'.
The keys unlocked safety for Amir and Iain Lee, meaning they will not face the first vote-off. More celebrities are expected to receive immunity before the vote to save opens.
Tune in to I'm A Celebrity… Get Me Out Of Here tonight at 9.00pm on ITV to see who's first to be voted out of the jungle.
