For years, Harleymoon Kemp called herself the invisible Kemp. She studied photography at the London College of Communication, built a career directing and shooting for artists and magazines, and spent years writing songs for other people rather than releasing her own. The distance between her life and the celebrity world occupied by her parents — Spandau Ballet bassist Martin Kemp and Wham! singer Shirlie Holliman — and her brother Roman was something she kept deliberately.
Then 2025 happened, and she was invisible no longer.
Her father appeared on I’m A Celebrity on ITV and spoke about the two brain tumours that had nearly killed him in 1995, reopening a story the family had never fully left behind. Her brother broke down on BBC One’s Celebrity Race Across the World to thank her for saving his life during a phone call she had taken years earlier, without fully grasping what it meant at the time. For weeks, the Kemp family’s health history played out across national television simultaneously.
Questions about Harleymoon Kemp’s own health followed. The answer is straightforward: she has no confirmed illness, no reported medical condition, and no health issues that she or her family have ever disclosed. The health story attached to her name belongs entirely to the people she grew up around — and it goes back thirty years.

A Childhood Shaped by Her Father’s Illness
Harleymoon was five years old in 1995 when Martin Kemp discovered a lump on the back of his head while working in Canada. He was 34. An MRI scan confirmed two benign brain tumours: one near the surface of the skull, a second sitting deep in the brain where conventional surgery was too dangerous.
Surgeons removed the surface tumour. For the second, Shirlie refused the initial prognosis and tracked down a non-invasive stereotactic radiation procedure at St Bartholomew’s Hospital in London. The treatment lasted 20 minutes and was a forerunner of what is today called the Gamma Knife. Martin told The Mirror: “Shirlie refusing to accept what the doctor said saved me.”
Recovery took three years. Martin could not work. The family relocated from Hampstead Heath to Muswell Hill. Shirlie was declared bankrupt in September 1996.
The lasting effects have never fully left him:
- Epilepsy — managed with daily medication. He has been a patron of the Encephalitis Society for years.
- Dyslexia — caused by brain trauma during surgery. He described it on Roman’s podcast: “I have dyslexia when it comes to thinking what street is in front of another street. That all goes back to the brain injury.”
- A protective metal plate fitted under his scalp after the operation.
The EastEnders role that began in December 1998 helped rebuild what the illness had taken. “It moved me forward and left that whole nightmare behind,” Martin said. He won three TV Quick Best Soap Actor awards, a National Television Award and five British Soap Awards during that run.
On September 4, 2009 — fourteen years after his diagnosis — he opened the London Gamma Knife Centre at St Bartholomew’s. In November 2025, on I’m A Celebrity Series 25, he told his campmates: “For a while I lost everything. I couldn’t walk, couldn’t talk, I couldn’t see in one eye. I was a train wreck afterwards.” He was voted off in seventh place.
Harleymoon grew up inside all of this. The diagnosis, the financial collapse, the slow recovery. It is the foundational experience of her childhood and the context that most people searching her name are missing entirely.
Six Weeks on the BBC That Brought Everything to the Surface
Celebrity Race Across the World Series 3 premiered on BBC One on November 6, 2025. Four pairs raced from Isla Mujeres in Mexico to the Península de La Guajira in Colombia on a tight budget, with no internet access. Harleymoon, then 36, was paired with Roman, 32.
In the November 20 episode, Roman told his sister over a quiet drink that he had stopped taking antidepressants after more than 15 years. He had been on sertraline since the age of 15 to manage depression and anxiety, and coming off it had left him experiencing emotions he had not felt for most of his adult life, including panic attacks. He told Harleymoon: “I’ve made the decision to come off them because I feel like I’m in a good place in life. Now it’s trying to discover what my actual emotions are.”
Her response, unscripted: “Prior to this trip, I guess I just thought you were a bit of a worrier for the sake of worrying. But I do feel like I’m getting to understand you better.”
The December 4 episode was harder. Roman broke down telling her about the night he had come close to ending his life — and the phone call she had taken years earlier, without knowing what was really happening. On camera, visibly emotional, he told her:
“I can’t even remember what the conversation was, but I knew that I was safe if I stayed on the phone. And I feel bad because I never really said thanks for that.”
On December 11, they won. The siblings ran the final stretch neck-and-neck with Molly Rainford and Tyler West, scrambling up a rocky cliff in Colombia and touching the checkpoint book first. Harleymoon described the finish afterward: “It’s the fastest I’ve ever run in my life. I’ve never run before, let alone been chased by the fittest couple in the world.”
For six weeks, she sat at the centre of a health narrative. Her family’s. Not her own.
The Career She Built Before Anyone Was Watching
Harleymoon Kemp was born in London on August 19, 1989. Her godfathers were George Michael, who died in December 2016, and Gary Kemp of Spandau Ballet. Despite growing up in one of British pop music’s most recognisable families, she spent her twenties working behind the camera, shooting for artists including Nothing But Thieves and for publications including Wonderland and Notion, and writing songs she never released under her own name.
The reluctance was rooted in a specific experience. At 18, she visited a record label with her own songs. She told CountryRadio.co.uk what happened: “I know they didn’t really listen to it and I felt scared of the name attachment. It really put me off. So I ended up going down a photography route and did music in the background for other people.”
That continued, quietly, for years. She wrote two of the songs on her parents’ joint album In the Swing of It, which reached number 12 on the UK Albums Chart in 2019, without most people knowing she was involved.
The lockdown of 2020 changed things. Her debut single “Space” hit number one on the UK Country Chart. She won Horizon Artist of the Year at the British Country Music Awards in 2021. Her 2024 single “What Good Looks Like” — written directly about watching her parents’ marriage — went viral, reaching 5.6 million views in a week. Jessie J publicly called it “beautiful, honest songwriting.” In September 2025, she performed the song as a duet with Ronan Keating at BBC Radio 2’s Party in the Park in front of 35,000 people.
Her October 2025 single “My Girls (love me better)”, written in Nashville with the Liz Rose Music team — known for their work with Taylor Swift and Miranda Lambert — premiered on Bob Harris’s BBC Radio 2 show and peaked at number 32 on the UK Official Singles Chart. She completed a four-date UK headline tour that December, with Una Healy and Hannah Jane Lewis as special guests at the London show.
In 2026, she is confirmed at Dornoch Music Festival on July 17 and the British Country Music Festival.
When Hello! magazine asked how she handles difficulty, she answered without hesitation: “I have this weird therapy gift in songwriting. When I need to reflect on something or feel tangled up, I hear it as a song, then I write it down and get it out of my system. I really am my own therapist.”
That is the clearest picture available of where Harleymoon Kemp actually is. A brother who is alive, in part, because she picked up the phone. A father who rebuilt his life after a diagnosis that should have ended it. And a musician who spent twenty years becoming herself before she let anyone watch.
