I'm A Celeb's Dean McCullough is 'as desperate for fame as Meghan Markle', claim insiders - as star shrieks through first Bushtucker Trial after being punished by viewers 'for sucking up to Coleen Roo

I'm a Celebrity star Dean McCullough has been branded 'as desperate for fame as Meghan Markle ' as the star takes on his first Bushtucker Trial.

The BBC Radio 1 presenter, 31, will enter the Sinister Sarcophagus during Tuesday's episode and a first look clip shows him in a sarcophagus shaped container with a separate box around his head.

He is tasked with answering questions relating to Egypt and as the container begins filling up with critters, he exclaims: 'Jesus boys. What on earth is that? Sounds like Coco Pops. Oh my god it sounds like Coco Pops.

'What on earth is that?' he wails. 'Oh my god what is that? Eugh, what is that?' And upon learning they are giant mealworms', Dean wails: 'Oh my god, no! No, this is hell.'

Ant then asks the first question: 'Complete this title of this 1980s pop hit by the Bangles. Walk like an..?' to which Dean correctly responds: 'Egyptian'.

Dean is then tasked with releasing stars using his mouth and passing them into various slots to win meals for his campmates.

I'm A Celebrity viewers voted Dean to face his first Bushtucker Trial after accusing him of being 'desperate to be in the limelight' and 'sucking up to Coleen Rooney.'

Industry insiders have since revealed that the radio star is 'super ambitious' and is 'determined to climb his way to the top'.

One source even went as far as to liken his determination to secure friends in high places to being like Meghan Markle.

'Dean is a super networker,' one told MailOnline. 'He will schmooze all of the agents, and basically anyone who can help him.

'Dean wants to make it, he puts the work in but he also knows how to climb and climb.'

Dean recently signed to top talent company MC Saatchi where one of those who represents him is Madison Lygo, the daughter of ITV's Director of Televison, Kevin Lygo.

One insider described Dean signing for the firm as a 'clever move.'

It comes after Dean confessed he wanted to befriend WAG Coleen while in the Jungle and fans have spotted the Northern Irish presenter has a habit of always being where the 39-year-old TV personality is in the camp.

Before entering the Jungle, Dean told MailOnline: 'Can you imagine what it's going to be like when I'm having my birthday next year.

'I'm like, oh yeah, you know, Coleen's going to be there and Maura. My friends are literally going to lose their s**t.

'Like, I've got celebrity friends, Like, "Oh sorry, I can't go to that, I'm just off to Lake Como with the Rooneys!".'

It comes after ITV viewers have pointed out on X, formerly known as Twitter, 'Dean is making sure he is in every single scene tonight.'

While others have accused him of 'craving airtime' for asking Coleen Rooney about her Wagatha Christie trial.
