ITV viewers were treated to another episode of I’m A Celebrity… Get Me Out Of Here! tonight (November 28), which saw one campmate open about a “fallout” in his family.

Jack Osbourne, who is best known for starring in MTV’s reality series The Osbournes with mother Sharon Osbourne, sister Kelly Osbourne and late father Ozzy Osbourne, spoke candidly to campmate Kelly Brook about his late grandfather Don Arden.

Don, a former famous music manager and father to Sharon, died in 2007 at the age of 81.

During his chat with Kelly, Jack revealed he hadn’t met his grandad until he was 17 years old, with Sharon having previously told him “he was dead”.

Kelly told Jack she’d heard a rumour Don used to dangle bands out the window unless they signed to him, with Jack adding: “He pulled guns on people, everything.”

He then went on to explain how Sharon had fallen out with her father after she took management of her husband, Ozzy.

Explaining how his grandfather reacted, Jack said: “He sent hitmen after them, mobsters would show up with guns at gigs…”

He added: “She was his protégé, he taught her everything and he did all sorts of screwed up things.

“Had my mum sign all these documents and everything was in her name so he would never get in trouble….they would firebomb other record companies. That’s why my grandfather knew the Krays.”

He explained that his mum Sharon eventually found out that her father had apparently been stealing money from bands at the time.

Jack then told the camp: “After she left and took management of my dad, they took them to court, they had to essentially pay him a million dollars to break the contract.”

Speaking about why he didn’t know his grandad until his teens, he admitted: “My mum actually told me he was dead…”

On the show, Jack has also previously spoken about his late father Ozzy, who sadly died in July at the age of 76.

He became overcome with emotion as he told campmate Eddie Kadi: “He had this force, so hard to describe. But he had this energy.

“It was like he swallowed the galaxy and didn’t know what to do with it. It’s the only way to ever describe it.”

Attempting to console Jack, Eddie told him: “What a man, your dad did more than enough.”

I’m A Celebrity… Get Me Out Of Here! continues tomorrow at 9pm on ITV1 and ITVX.
