Sharon Osbourne nervously tuned in to see her son Jack complete his first solo trial in the I’m A Celebrity Get Me Out Of Here! jungle on Tuesday.

Joined by her daughter Kelly, the pair admitted they were ‘holding their breath’ as they saw Jack take on the underwater challenge, Drown The Hatch.

Documenting their reactions on Instagram Stories, Kelly admitted her brother must have been ‘so exhausted’ completing the challenge, where he had to dive down underwater in eight different chambers to search for stars hidden in hatches.

But despite the physically gruelling nature of the trial, Jack made light work of it, leaving even hosts Ant McPartlin and Declan Donnelly impressed as he won a full house of 12 stars in record time.

It came after Kelly hit out at Jack’s campmate Kelly Brook last week over a ‘performative’ clash she’d had with him over gutting a fish, branding the model a ‘bully’ in a fiery social media post.

Kelly shared a string of videos of herself and Sharon reacting to the trial while watching it on TV, and were left on edge as the episode cut to a break mere seconds after the challenge began.

Joined by her daughter Kelly, the pair admitted they were ‘holding their breath’ as they saw Jack take on the underwater challenge, Drown The Hatch

She told her followers: ‘Watching I’m A Celeb and they cut to commercial at the most poignant bit and I was holding my breath, and I realised halfway through the first commercial I was still holding my breath.

‘Come on, he’s in a chamber of water, and he only has two minutes!’

As Sharon added he was surrounded by ‘lobsters and toads,’ Kelly said: ‘We need to know what’s happening!’

Despite the task at hand, Jack breezed through the first chamber, collecting his first two stars in just 26 seconds.

As Jack headed into the third chamber, Kelly said: ‘He’s doing so well! He’s doing so well! Yes Jacky! Come on Jacky, come on Jacky you’ve got one more star to get!’

Sharon added: ‘He has got to be exhausted.’

‘Jack has found his zen Oh my god! A minute holding his breath on that one,’ Kelly went on to say.

As Jack made his way in to the final chamber, Kelly added: ‘He’s doing so well Mum he’s doing so well!’

She and Sharon celebrated as Jack completed the trial with a full house of 12 stars, telling her followers: ‘He got the camp an amazing dinner, and we are so proud of him. I think I was more nervous than he was but he did f*****g amazing and we are so so so proud, so proud.’

Joining in with the camp who branded Jack ‘Jack-qua man,’ she added: ‘Sorry I think I spelt Jacqwaman wrong, but that’s his name now! Jaquaman!’

Fans were also very quick to take to social media to praise Jack for ‘bossing the trial’ with many saying how ‘insanely impressed’ they are.

They wrote: ‘I have to say I’ve NEVER seen anyone boss a trial the way Jack Osbourne bossed his trial tonight!; Calling Jack Osbourne nothing but “jaquaman” for the rest of the series;

‘Jack Osbourne is doing amazing on #ImACeleb. That trial would terrify me; Jack Osbourne with the healthy lungs!

‘THAT WAS INSANE!! JACK OSBOURNE, YOU SMASHED IT LIKE A BEAST!!; Jack Osbourne i’m insanely impressed;

‘Jack Osbourne seems to be able to hold his breath underwater for an inordinately long amount of time!’

Kelly has proudly supported her brother on social media during his time in the I’m A Celebrity jungle, and last week blasted his campmate Kelly Brook for a ‘performative’ on-screen clash with him.

The 41‑year‑old took aim at Kelly in a fiery Instagram Story, accusing the TV star of being ‘overly dramatic’ following her gagging reaction while gutting a fish.

Jack, Kelly’s younger brother, had stepped in to help his campmate as she struggled to prepare dinner, politely asking: ‘Would you like me to cut up the fish?’

Although Kelly, 45, accepted his offer, she later claimed to camera that Jack had ‘elbowed’ her aside, saying: ‘I saw Jack’s eyes light up, it was like Christmas to Jack, and he came running over and elbowed me out of the way to get to this fish like a caveman, and I was like, no, I’m going to do it.’

Kelly then insisted on chopping the fish herself but repeatedly gagged and retched at the smell, prompting Osbourne to slam her behaviour as ‘performative’.

Osbourne has now leapt to her brother’s defence, admitting the exchange triggered her ‘protective’ instincts and even made her feel like ‘attacking’ the Heart Radio presenter for her tone.

Speaking on Instagram, she said: ‘Kelly Brook… I don’t think I like you. Elbowing out of the way to get to the fish… you’re so performative, with all the gagging and the over‑dramatics.

‘You bring out my big‑sister vibes where I want to attack you because I feel like you’re a bit of a bully.’

Jack has impressed viewers since he entered the jungle earlier this month with his sheer willingness to get stuck into the more difficult aspects of jungle life

The disagreement over the eel led Osbourne to unleash her fury on Kelly, accusing the former glamour model of reacting badly to her brother’s offer of help and describing her as a ‘bully’.

Since arriving at camp, Jack has taken a hands-on approach, lighting the fire and helping prepare meals, a style he says comes from growing up in a big family and raising four children of his own.

His sister Kelly may also be feeling especially protective, following the sudden loss of their father, Ozzy, who passed away in July.

During his time in the jungle, Jack has opened up to campmates about his grief, reflecting on his father’s legacy.

He has shared memories of Ozzy’s iconic final show this summer and laughed about his wild antics, including famously biting the head off a bat, noting how such behaviour would be frowned upon in today’s society.
