Television personality Kelly Osbourne has launched a fierce defence of her brother, Jack Osbourne, after witnessing his tense interactions with fellow I'm A Celebrity... Get Me Out Of Here! contestant Kelly Brook. The 41-year-old took to Instagram to express her fury, directly calling out Brook's behaviour in the jungle as 'performative' and 'bullying'.
Jungle Kitchen Clash Sparks Family Feud
The drama unfolded during the episode aired on Wednesday, November 20, 2025. The conflict began when Kelly Brook, 45, expressed dissatisfaction with Jack Osbourne, 40, taking charge of the camp's kitchen. Jack had put himself forward as head chef, a role other campmates were happy with given the unappealing nature of the food tasks.
Viewers saw Brook volunteer to help prepare the camp's dinner, which on this occasion was a raw eel. However, she was repeatedly shown gagging and retching at the smell of the fish. Ultimately, Jack stepped in to offer assistance with cutting up the eel, which Brook accepted.
The situation escalated later when Brook sat down in the ITV diary hut. She claimed that Jack had 'elbowed' her out of the way 'like a caveman' to get to the fish. This version of events prompted a strong reaction from outside the jungle.
Kelly Osbourne's Furious Social Media Reaction
In a video posted to her social media account, Kelly Osbourne did not hold back. Speaking directly to the camera, she addressed Brook, who remains unaware of the comments while isolated in the Australian jungle.
'Kelly Brook, I don't think I like you,' Osbourne stated. 'Elbowing out of the way to get to the fish. You're so performative, with all the gagging and the over-dramatics.'
She went on to explain that Brook's actions had triggered her protective instincts. 'You bring out my big-sister vibes where I want to attack you because I feel like you're a bit of a bully.' This powerful statement highlights the depth of feeling the jungle antics have provoked within the Osbourne family.
A Pattern of Tension in Camp
This was not the first sign of friction between the two campmates. The evening before the eel incident, there were already frosty scenes in the camp. Brook had again shown unhappiness with Jack's self-appointed role as chef-in-chief.
The tension peaked when Jack pointed out that Brook was using the wrong size knife to peel potatoes. This seemingly minor correction appears to have been part of a broader power struggle over the camp's culinary duties.
ITV viewers are now speculating that this could be the start of the first major feud of the 2025 series. With Jack being the son of rock legend Ozzy Osbourne and Kelly being a well-known media personality, the clash has all the ingredients for a headline-grabbing storyline.
As the campmates continue their jungle experience, all eyes will be on the kitchen to see if the tension between Jack Osbourne and Kelly Brook simmers down or boils over into a full-blown row.
