I’m A Celeb’s Ant McPartlin barked ‘face your fears!’ at a screeching Dean McCullough in a chaotic first look at Monday’s Bushtucker Trial.

The BBC Radio 1 presenter will take part in Jack and the Scream Stalk tonight after fans put him forward for yet another trial.

Dean, 32, had to retrieve gold stars from critter-filled boxes, called ‘hell holes’, as he climbed up a ‘bean stalk’ made of scaffolding to reach a castle.

In a sneak peak of the trial, Dean squealed and screamed ‘no, no, no!’ as he plunged his hand into a box full of tarantulas.

Ant McPartlin, who has shown ‘annoyance’ towards Dean’s previous efforts in past trials, shouted: ‘You can do it! Face your fears!’

It comes after the host, 49, struggled to hide his frustration last week when Dean quit another challenge that saw him drenched in fish guts.

Viewers noticed that during Thursday’s show, Ant was ‘lowkey mad’ at Dean for ‘not trying properly’ in his first two trials and so urged the radio host to ‘try harder’.

Ant addressed his reaction during an appearance on spin-off I’m A Celebrity: Unpacked, saying: ‘My annoyance came across on screen and I was quite unprofessional. You get to the point where you’re like, “What are you doing?”‘

As Dean arrived at his third trial in three days, Ant and Dec ran through the rules of Lethal Lab, adding he will be joined by cockroaches, crickets and meal worms, giant lizards, snakes and spiders.

Ant said: ‘Now Dean, I want to have a word with you. What happened yesterday? No stars. What happened the day before? You said I’m A Celebrity… Get Me Out Of Here. You can only change the narrative by sticking with it and getting on with it.’

During the very stern chat, Dean said to Ant: ‘I feel like I’m being told off by Ant and Dec.’

Dean called ‘I’m A Celebrity… Get Me Out Of Here’ half way through the trial after getting spooked from fish guts.

With spiders on his head, snakes around his neck, green ants in his arms and cockroaches around his head, it all got too much for Dean when fish guts smothered the back of his neck.

Dean has repeatedly been voted in by the public to take part in the shows Bushtucker Trials

Dean had two minutes to complete an experiment, worth 2 stars, in the experimentation area.

He then had to make his way through seven different containment areas, where a further eight stars were up for grabs.

Dean told Ant and Dec: ‘I like to over-promise and under-deliver.’

During the first experiment, he had to combine both a green liquid and a clear liquid into the test tube together to create a chemical reaction.

Half way through the trial, he said: ‘This is not looking good boys.’

As he successfully created a chemical reaction by combining the two liquids, he won two stars for camp and moved on to the containment areas.

After winning two more stars in containment areas one and three, he then moved onto area five.

As fish guts poured into the compartment, Dean immediately shouted: ‘I’m A Celebrity… Get Me Out Of Here!’

I’m A Celebrity host Ant McPartlin has admitted that he was ‘unprofessional’ during Dean McCullough’s latest trial, after fans clocked his ‘furious’ reaction to the DJ quitting yet again

The Radio 1 host has consistently been chosen by the public to do the challenges and Ant McPartlin couldn’t hide his frustration after he quit once again

Viewers noticed that during Thursday’s show, Ant was ‘lowkey mad’ at Dean for ‘not trying properly’ in his first two trials and so urged the radio host to ‘try harder’ 

Talking to viewers after the trial aired, Ant said: ‘What the b***** h***, he only gets four stars and they pamper him. It’s not good is it, he literally got four out of ten!’

Ant slammed Dean after the radio DJ failed to win any stars during his trial with GK Barry on Wednesday evening.

The duo took part in the Down In The Drumps trial as they were forced to face their fears while working together to secure meals for camp.

However the pair failed to win any stars, and Ant didn’t hold back as he vented his frustrations during the show’s spin off I’m A Celebrity Unpacked.

As host Joel Dommett began: ‘Let’s talk briefly about today’s trial,’ Ant interjected with: ‘Oh god.’

Letting his feelings be known he explained: ‘I got quite annoyed at one point because I am a bit like, if you can’t do it you can’t do it, but just get on with it. Just try it, try it.

‘If it is physically impossible or you find it physically hard that’s fine but at least try. There was a lot of not trying for quite a few minutes until they started to try and then they ran out of time.’

As Dean arrived at his third trial in three days, Ant and Dec ran through the rules of ‘Lethal Lab’, adding he will be joined by cockroaches, crickets and mealworms, giant lizards, snakes and spiders

Ahead of the trial, viewers also noticed Ant was ‘lowkey mad’ at Dean for ‘not trying properly’ in his first two trials and so urged the radio host to ‘try harder’

Dean and GK were left shaking and in tears after Wednesday’s trial and as Ant and Dec counted down the seconds to go, Grace got spooked by an eel and screamed: ‘I’m done, I’m done!’ 

Sam Thompson then agreed as he added: ‘What you are saying as well is you are standing screaming at nothing at this point in time, like you are just getting rained on.’

Ant agreed: ‘Yeah you are screaming at water.’

During Dean’s trial on Tuesday he exclaimed: ‘I’m a celebrity get me out of here’ after being submerged in a box of sand.

Referring to the previous trial, Sam joked: ‘It really makes me think like Dean, sand and water, what is it like when he goes to the beach? I have never seen scream so much without touching anything.’

Meanwhile the host also admitted to MailOnline: ‘A lot of people appear frustrated at Dean, well as frustrated as I was, but I felt I held it together pretty well. We miss Tony Bellew, he would have smashed that trial.’

I’m A Celebrity… Get Me Out Of Here! airs on ITV1 and ITVX.
