Medics were forced to rush into camp when Matt Hancock yelped in pain after he was stung by a scorpion.
The creature attacked the MP shortly before breakfast today and nipped him unexpectedly leaving him yelping in pain.
A show source said: "Matt didn't see the scorpion until it was too late and it bit his finger. He felt a lot of pain and made a yelping noise, but thankfully for him there was no lasting damage.
"Medics checked him over and gave him a clean bill of health but the whole camp is now watching out for them.
"Matt was saying afterwards it felt twice as painful as a bee sting."
While Australian scorpions can give you a nasty sting if you step on one or take it by surprise, their venom is not deadly.
Associate Professor Bryan Fry, from the University of Queensland's School of Biological Sciences, told ABC news: "Typically, the sting is minor localised pain and a tiny bit of swelling — usually quite trivial effects.
"As far as the pain sensation, the sting would normally be similar to a bee and dramatically less than that of the bullet ants that we have in Australia."
Some fans may have heard Babatúndé Aléshé make reference to the incident on air at the very end of Saturday night's show after it was revealed Matt would be doing the next Trial.
He said "Do you know what Matt, you are the man, you are the man, four trials and you got stung by a scorpion and you have to go do a trial."
The scorpion was safely removed from camp following the attack to avoid further campmates being stung.
Black Rock Scorpions, which are the most common in New South Wales where I'm A Celeb is filmed, are found in shallow burrows (10cm deep) in earth or sand in open forests and woodlands.
The burrow is found under rocks and logs and the entrance is usually covered with a stone.
Viewers will see the incident on the show tonight, where Hancock is also taking part in his fifth trial, House Of Horrors.
I'm A Celebrity continues on Sunday night at 9pm on ITV.
