Kelly Osbourne has said her piece on her brother Jack’s brewing feud with Kelly Brook on I’m A Celebrity...Get Me Out of Here!
The 41-year-old shared a brutal video on Instagram, labelling Ms Brook a “bully” and “performative”.
The scathing post comes just days into this year’s series of the ITV show, where the camp has largely been getting on well together.
However, Mr Osbourne and Ms Brook seem to be facing an unspoken rift - one which has prompted his sister to admit she "wants to attack" the actress.
The pair got off to a poor start after TV personality Mr Osbourne, 40, took matters into his own hands when it seemed none of his fellow campmates could cook.
When the actress was peeling potatoes as he cooked, he informed her she was using the wrong knife to peel, which seemed to offend Ms Brook.
Addressing how she felt, she told Mr Osbourne the following morning: “I just want to be so useful.
“I’m just still trying to find my place in the camp in terms of what to do, and so I’m so sorry, Jack, if I’m coming at you and if I’m cutting potatoes wrong, but honestly, it’s only coming from a place where I just want to help.”

Mr Osbourne agreed to take a step back and vowed to allow others to cook on Tuesday.
However, during Wednesday’s show, Ms Brook asked him for assistance when it was her turn to prepare the camp’s meal, and she struggled to gut an eel.
Mr Osbourne, experienced in cooking fish, took over, but it soon appeared Ms Brook was unhappy about being demoted from chef.
Realising this, Mr Osbourne once again left the fish and allowed her to continue, but soon she was gagging and close to throwing up from the task.

"I told you,” Mr Osbourne remarked before he took over once again to sort the camp’s dinner.
Despite his help, Ms Brook later claimed in the Bush Telegraph: “It was like Christmas to Jack. He came running over and was like elbowing me out of the way to get to this fish.
"Like a caveman! And I was like, 'No, I'm going to do it.'"
Ms Osbourne didn't take kindly to her brother being bad-mouthed and didn't hesitate to share her thoughts on social media.
