The 25-year-old star, whose real name is Harrison James Armstrong, revealed that his decision was driven entirely by one person: his little sister Gracie, the 13-year-old he describes as “the most perfect girl I’ve ever met.”

A Mission Bigger Than Himself

Speaking with raw honesty, Aitch shared that he is stepping into the jungle not for publicity, but to change how the world sees Down Syndrome — and to support families who might feel fear or uncertainty after receiving a diagnosis.

Family games

He wants parents to know they haven’t been handed something tragic.

“It’s a blessing,” he said firmly.
“You’re going to have the best time of your life as long as you’re spending it with that person.”

For Aitch, this isn’t a campaign — it’s a duty. He refuses to let Down Syndrome be spoken about as if it were a burden, a mistake, or a shadow on a family’s future.

“They’re the best people in the world,” he added, his voice carrying both pride and protectiveness.

A Brother’s Love That Changed Everything

Aitch’s bond with Gracie has long been known to fans. His hit track My G — whose profits all go to the Down’s Syndrome Association — was written entirely as a tribute to her.
The song begins with a heartfelt message: “You have the biggest heart in the world! Don’t change for no one.”
It even features Ed Sheeran in the music video.

But his jungle appearance marks the first time he’s openly linked his career choices to his sister’s future.

He admitted that he didn’t tell Gracie he was joining the show because she’d “absolutely spill the secret,” laughing that she thinks he’s flying to LA instead. When she finally sees him appear on-screen, he expects a huge grin and a simple:
“That’s Harrison!”

A Difficult Truth He Couldn’t Ignore

In one of his most emotional revelations yet, Aitch spoke about how deeply disturbed he was after learning about the UK’s abortion laws regarding Down Syndrome.

He didn’t shy away from the controversy.

“It makes me sad,” he admitted.
“You can be a day away from giving birth and still have the option to terminate if you find out your child has Down Syndrome… but if your child doesn’t have it, you’ve only got a short window.”

He shared the thought not to provoke anger but to spark reflection — to challenge how society assigns value to certain lives and not others.

The Jungle Awaits — And So Does a Bigger Platform

While raising awareness is his main purpose, Aitch also admitted that the series is impossible to turn down.

“I grew up watching it,” he said. “My mum would’ve gone mad if I said no.”
He hopes the show will also open the door to future  TV opportunities.

Joining a high-profile cast that includes Jack Osbourne and Kelly Brook, Aitch is already one of the most talked-about names of the season.
But it’s not his music, fame, or fanbase that’s capturing hearts.
