Media personalities Princess and Junior Andre, singers Sam Ryder and Ella Eyre, and broadcaster Jeff Stelling will take part in the new series of the BBC's Celebrity Race Across the World.
Four teams of two leave their phones and home comforts behind as they attempt to become the quickest to reach a destination without using air travel.
Princess and Junior Andre, the children of former model Katie Price and her ex-husband Peter Andre, will compete together.
Singer Eyre will be joined by her childhood friend Nana.
Fellow singer Ryder will embark on the trip alongside his tour manager Kaz Coles.
Sky Sports presenter Stelling will compete with his son Matt.
The teams will set off from the city of Kuching, Malaysia.
They will have to reach five checkpoints across three countries and two continents, ultimately aiming for the southern tip of Australia and the finish line in Melbourne.
The teams will need to rely on their own resourcefulness, local transport, and the kindness of strangers to make it further into the race, equipped with only a map and a budget of just £26 per person a day.
Chief Creative Officer of production company Studio Lambert, Tim Harcourt, said: "This year's pairs navigate a journey that lays bare two extremes of today's world.
"We can't wait to share how they get on. Contestants give unfiltered and honest reactions to the experiences they face that are as demanding as they are joyful.
"That's so rare on television and it's clear audiences love seeing their favourite stars deal with these daring challenges in spectacular worlds."
Race Across the World will return to BBC One this autumn.
