“Yesterday was a bit of a delicate day for me…” said Jack Osbourne on tonight’s I’m A Celebrity. “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.”

That’s Jack’s appeal in a nutshell: his heart is on his sleeve, and he’s never afraid to articulate his emotions, even when they’re uncomfortable. (The mark, we’d surmise, of a man who’s benefited from therapy.)

He’s been keeping the nation entertained with his heartfelt campfire chats and impressive outdoor survival skills since the start of the series. 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.

He’s an essential part of this year’s mix! But who is this guy? Let’s find out…

Jack Osbourne’s partner: is Jack Osbourne married?

Yes, he’s been married to interior designer Aree Gearhart since 2023. Before that he was married to Lisa Stelly from 2012 to 2019.

How many children does Jack Osbourne have?

Jack has four daughters. Three are from his previous marriage to Lisa Stelly (from 2012-2019): 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.

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.

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

What was Jack Osbourne’s addiction?

During his time on I’m A Celebrity, Jack has opened up about the death of his father, Ozzy Osbourne, in July this year, telling his campmates that his grief is still fresh and something he struggles with daily. Jack has also talked about his addiction struggles in his teens.

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?

Most people know Jack has a sister, Kelly, 41, who is as famous as he is, having also appeared in The Osbournes. But the pair also have a sister called Aimee, 42, who made the decision not to appear in the show.

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.

He has also starred in Portals to Hell, Jack Osbourne’s Haunted Homecoming and Jack Osbourne’s Buried Bloodlines.

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.

His accent is a mix of British and American 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.

Jack has been a vital part of I’m A Celebrity so far, with his campmates affectionately calling him Jungle Jack – but will his cooking and fire lighting skills be enough to see him crowned King of the Jungle?
