You'd never guess that coming from one of the most riotous, rock 'n' roll families in entertainment that Jack Osbourne would become one of the most stable and grounding forces in the I'm A Celebrity camp.

Over the course of the past few weeks in the Australian jungle, Jack has cemented his appeal with a legion of old and new fans, who have enjoyed watching this older, wiser Osbourne create a whole new legacy for the family.

But alongside the heartfelt campfire chats and impressive outdoor survival skills, he's also opened up about his family life, about losing his late father Ozzy in July, and the battle he’s faced to stay sober – 20 years and counting.

As we head towards the final furlong of the competition, what else is there to know about the man who could well be crowned King of the Jungle? Here's all you need to know about our favourite British-American contestant:

Jack Osbourne's partner: is Jack Osbourne married?

Yes, and interior designer Aree Gearhart is his second wife. The pair got engaged in 2021, and married in San Ysidro Ranch in California in 2023.

Before that, Jack married to actor Lisa Stelly from 2012 to 2019.

What to Read Next

How many children does Jack Osbourne have?

Jack has four daughters. Three are from his first marriage to Lisa Stelly: Pearl Clementine, 13, Andy Rose, 10, and Minnie Theodora, 7. He also has a daughter with Aree, Maple Artemis, who was born in 2022.

Jack has talked about his children since arriving in the Australian jungle, explaining to his campmates that he shares custody of his eldest three daughters with his ex-wife and sees them regularly.

On Thursday night's show, he also gave a little peek into life at home with his kids - and how strict he is with them.

Talking with the other campmates Jack shared that he had a very modern way of disciplining his kids: he takes their iPads off them, saying "that's mine now". As they moan: "Well what are we doing to do now?" he tells them to “read a book”. Which sounds utterly reasonable to us.

He also said that he revels in being a dad, and that having kids is "great...so much fun".

In Kelly Brook's post-jungle stay in the IAC friends and family hotel, she revealed that she'd spoken with his wife Aree – and that she felt vindicated about the camp spat with Jack over gutting a fish, as Aree confirmed he was a bit of a back-seat chef at home.

Speaking on Unpacked, Kelly said: "I caught up with Jack's wife, we had breakfast together this morning. She [Aree] said, 'Thank goodness because whenever we are cooking in the kitchen he's always over my shoulder telling me what to do, telling me to turn the oven down a bit.'"

Aree then apparently continued: "Thank goodness now that I've got it on film so we can see that he does it to everybody."

"It wasn't just me," Kelly reasoned, before adding that she and Jack "did have a lovely relationship" in the jungle.

What happened to Ozzy Osbourne, Jack's dad?

Jack's much-loved dad, Black Sabbath rocker Ozzy Osbourne sadly died of a heart attack earlier this year. And Jack marked four months since his dad passed while in the jungle.

“Yesterday was a bit of a delicate day for me…" said Jack. "I was doing okay, and then I realised it was the four months since my dad died. I had a good cry with Eddie, but ultimately I’m happy, I’m really happy I’m here."

What illness does Jack Osbourne have?

Jack was diagnosed with relapsing-remitting multiple sclerosis in 2012 when he was just 26 years old. MS is a chronic neurological condition that damages nerves and affects the transmission of messages to different parts of the body. The NHS describes relapsing-remitting MS to be the most common type of the illness. In an nutshell, it's a form of the disease that comes and goes, especially in times of stress.

In 2023, Jack revealed that he manages his condition by taking Copaxone medication daily, that he does hormone replacement therapy, and has travelled to Europe for stem cell therapy.

Jack opened up about his condition on The Osbournes podcast recently, admitting that he was diagnosed shortly after his eldest daughter, Pearl, was born in 2012, making the timing particularly tricky.

What was Jack Osbourne's addiction?

During his time on I’m A Celebrity, Jack has been open about his struggles with addiction when he was younger.

The TV star chatted with Emmerdale’s Lisa Riley about giving up drink and drugs ("pills and weed"), telling her that growing up on television meant he had a different childhood to most people: "There wasn’t a lot of structure and too much abundance and freedom. When you give a 16-year-old a ton of money and not a lot of rules in LA, you’re just going to go and play. I got sober when I was 17."

He then went on to explain that he went to an adolescent treatment centre in California and has been clean for the last 20 years.

How many siblings does Jack have?

Jack and his sister, Kelly, 41, grew up in front of the camera with one of the first reality family TV series ever, The Osbournes. But not a lot of people know that there's actually a third sibling, an older sister called Aimee, now 42, who declined to be on the show with her family.

Speaking on the Disrespectfully podcast earlier this year, Jack said that he'd never had the conversation with Aimee about why she wanted to stay out of the limelight, and revealed there was a gap between the siblings: “I’ve never had the conversation with her; we’re not close at all. We don’t have a great relationship, she’ll be the first to tell you that, so it’s no secret."

Jack also has three other older siblings from Ozzy’s first marriage to Thelma Riley: a sister called Jessica, 53, a brother called Louis, 50, and an adopted brother, Elliot, 59.

Jack Osbourne's TV career

Jack shot to fame in 2002 on the MTV fly-on-the-wall show The Osbournes, which he starred in with his parents, the late Black Sabbath legend Ozzy and music-manager mum Sharon, and his older sister, Kelly. The show was an instant hit and set the foundations for many reality TV series to come. It was also MTV’s most popular show at the time.

Since then, Jack has made a successful TV and film career appearing in movies like New York Minute with Mary-Kate and Ashley Olsen, Austin Powers in Goldmember and the show Super Mega Cakes. His endless TV credits include Dancing With The Stars in 2013 and 2023’s survival show Special Forces: World’s Toughest Test. He also recently appeared in series 5 of ITV’s Cooking with the Stars, where he came second to series winner Natalie Cassidy.

Jack is also a dab hand behind the camera, having produced and executive-produced films about his family from Osbournes Reloaded, which came out in 2009, to the most recent movie, The Nine Lives of Ozzy Osbourne, which was released in 2020.

The TV star is also fascinated by the paranormal and has produced and starred in shows about the subject including Jack Osbourne’s Night of Terror in 2022, where he spent a night sleeping in a tent in the woods trying to get a glimpse of Bigfoot.

Where is Jack Osbourne from?

If you’ve noticed that Jack’s accent flits from British to American, then there’s a good reason for that. Jack spent the first six years of his life in Buckinghamshire in the UK, before his family made the move to LA.

He's got that Mark Ronson-type, transatlantic drawl, thanks to his dad Ozzy hailing from Birmingham, while his mum, Sharon comes from London. During Jack’s childhood the family put down roots in Beverley Hills where he grew up and has lived ever since.
