Lee Mack and Holly Willoughby are to host 'Wim Hof's Superstar Survival'.
The TV presenters will join forces next year for the BBC One entertainment series, which will follow a group of soul-searching celebrities as they embark on an adventure of self-improvement under the guidance of well-being icon Wim Hof.
Holly said: "I can't wait to team up with Lee and Wim on this show.
"Lee is a favourite in our house because he's so hilariously funny and I've been a fan of Wim for a long time – he's a genius who's incredibly passionate about helping others.
"This show is going to be brilliantly entertaining and you never know ... you may find out some things that could help you along the way too."
Lee added: "My passions in life are Wim Hof, watching 'This Morning' in my undies, sub-zero temperatures, looking at celebrities sitting in cold water and free hotels.
"But trying to find a show that combines these has proved tricky. Finally I've found one."
The six-part series will see the celebs face a unique test of mental strength, including taking on death-defying challenges in Europe's harshest conditions.
And a BBC Three sister show will delve deeper into the challenges faced by the stars.
Wim - who is known as The Iceman - said: "I've dedicated my life to discovering how to become happier, healthier and stronger, and anything I can do, you can do too.
"It's a dream come true to be making this show with the BBC and share what I've learnt with millions of people.
"I am going to show this group of celebrities that the cold is a doorway to their soul and if they use the power of their mind anything is possible."
Wim has a huge celebrity following, including the likes of Tom Cruise, David Beckham, Oprah Winfrey, and Justin Bieber.
He has taken on huge challenges in his life, such as running a half marathon above the Arctic Circle barefoot, submerging himself in ice for an hour and 52 minutes, and climbing Mount Kilimanjaro in just his shorts and shoes.
Kate Phillips, Director of Entertainment at the BBC, added: "'Wim Hof's Superstar Survival' will put celebrities through their paces like never before.
"I'm looking forward to seeing how they cope with such extreme challenges under the watchful eye of the ultimate Cold King, Wim Hof.
"With Lee and Holly guiding us through, and taking it very seriously of course, it promises to be a very funny, and frosty watch!"
