What Does Harleymoon Kemp Do for a Living?

Her career in photography and film

Her background in visual production helped shape her creative approach to music.
In a 2026 interview with CountryMusic.co.uk, she explained that photography, filmmaking and songwriting share an important quality: they all involve telling a story.
She has continued to work on film projects alongside her music career.

Harleymoon later turned her attention to country music, developing her sound through songwriting and visits to Nashville.
Her debut single, Space, reached number one on the UK country chart, helping establish her as a recording artist.
She has subsequently released songs including My Girls (Love Me Better) and Wash.
Her music frequently explores relationships, friendship and personal experiences, combining country storytelling with contemporary pop and rock influences.
In September 2026, she discussed plans for a new EP and a more energetic musical direction inspired by her live performances.
Roman Kemp and His Sister Won Celebrity Race Across the World
Roman and Harleymoon appeared together in the third series of the BBC’s Celebrity Race Across the World in 2025.
The programme challenged celebrity pairs to travel long distances with limited resources, without relying on the usual conveniences of modern travel.
The brother-and-sister team raced across Central America, travelling from Mexico towards Colombia.
After completing a journey of approximately 5,900 kilometres, they won the competition, narrowly beating fellow contestants Molly Rainford and Tyler West.
Their victory introduced Harleymoon to viewers who were more familiar with Roman’s television and radio career.
The experience also allowed the siblings to spend extended time together away from their usual professional commitments.
Speaking about the programme in subsequent interviews, Harleymoon reflected on the opportunity to disconnect from everyday pressures and experience something different with her brother.
Are Roman and Harleymoon Kemp Close?
Roman and Harleymoon have publicly described a close family relationship.
In a 2017 interview with the Evening Standard, Roman said he regularly spoke to his parents and sister, explaining that they supported one another’s careers.
Harleymoon has also shared childhood memories of their relationship.
In a 2025 interview with Musik Magazine, she recalled listening to music with Roman when they were younger, including Eminem, Craig David, Sum 41 and Linkin Park.
She remembered how Roman could memorise song lyrics after hearing them only once.
Their appearance on Celebrity Race Across the World offered another glimpse of their relationship, as they navigated difficult journeys and made decisions together.
Following their victory, they reunited for a December 2025 episode of Roman’s You About? podcast to discuss their experiences and what they had learned about each other.

How Has Her Famous Family Influenced Harleymoon’s Career?
Music was part of Harleymoon’s upbringing, with both parents having established careers in the entertainment industry.
However, she did not immediately follow them into performing.

In a November 2025 interview with Musik Magazine, Harleymoon explained that she had been writing songs for years before deciding to pursue singing professionally.
She also described how learning guitar and spending time in Nashville helped her discover her own country music style.
Her career therefore combines her family’s musical background with interests she developed independently.
