Who are Roman and Harleymoon Kemp? Meet Celebrity Race Across the World 2025 contestants

It's time for the penultimate leg of Celebrity Race Against the World 2025, and it is the longest one so far.

Tonight (4th December), the teams must travel from the islands of Bocas del Toro on northern Panama's Caribbean coast to Medellín, Colombia's second-largest city.

But standing in their way is the notorious and dangerous Darién Gap. For the teams, their only option is to bypass it by sea, all while enduring a lengthy and costly boat journey, which could put their dwindling budgets under pressure.

Among the teams are brother-and-sister duo Roman and Harleymoon Kemp, who this week, are confronted with a heightened security risk on the route to Medellín...
As the race continues, here's everything you need to know about contestants and siblings Roman and Harleymoon Kemp.

Roman Kemp is a 32-year-old radio DJ and presenter, best known for hosting the breakfast show on CapitalFM from 2017 to 2024.

He is taking part in the race alongside his older sister, 36-year-old Harleymoon, who is a singer/songwriter. Roman and Harleymoon are the children of musicians Martin Kemp and Shirlie Holliman, who independently found success in the '80s as part of the bands Spandeau Ballet and Wham! respectively.
Roman struggled with the language whilst racing through the South American continent, telling Radio Times magazine that he kept "mistakenly telling everyone Harley was 'my beautiful' – mi hermosa – instead of 'my sister' – mi hermana – for at least a week."

Why did Roman and Harleymoon want to take part in Celebrity Race Across the World?

When asked if he had considered taking his famous dad rather than his sister on the show with him, Roman only had one thing to say: "No way!"

He continued: "I am very lucky that I do a lot of stuff with my dad, and I think that the reason I do those things is I can't wait to show my kids or my grandkids what my relationship was like with my dad. With this, it's such a privilege to be able to do something so special with your sister.

"It's such a privilege to be able to have that and to also show that to future generations and to share an experience. The other side of it is for personal reasons, travelling and seeing new places and seeing different cultures or being in certain experiences has such a great impact on my perspective and what life is about."

Harleymoon also revealed to Radio Times magazine that their mum had previously been asked to go on the show.

"My mum [Shirlie Kemp, a former backing singer for Wham! and half of Pepsi & Shirlie] was asked to be in the first celebrity Race across the World and was going to take me, but thought it sounded too hard. I was glad to have another chance to go," she said.

Celebrity Race Across the World continues on BBC One and iPlayer on Thursday 4th December at 8pm.
