Spencer Matthews is among the celebrities taking part in the new series of the BBC's Pilgrimage.
Returning to BBC Two next month, the new series will see "seven well-known personalities, of differing faiths and beliefs, tackle a modern-day pilgrimage, this time along the North Wales Pilgrim's Way".
The BBC continued: "Immersing themselves on this spiritual journey are: wildlife presenter Michaela Strachan, who places her faith in the natural world; Spencer Matthews, a former reality TV star turned entrepreneur, who was christened Church of England but is still searching for answers to life's big questions; Sonali Shah, a journalist and TV presenter who was raised in a Jain household; comedian Eshaan Akbar, a lapsed Muslim; Amanda Lovett, a practising Catholic, who catapulted to public attention in the first series of BBC's The Traitors; actor Tom Rosenthal, star of Channel 4's Friday Night Dinner, who calls himself 'areligious'; and TV personality and former model Christine McGuinness, who is spiritual but doesn't practise one particular faith."
Discussing why he chose to take part in the three-part series, Matthews told the BBC: "A pilgrimage is when you walk and sleep on church floors and eat dead rats and stuff, which I'm looking forward to.
"I'd be pretty low in the faith knowledge bracket, but I'm on a quest to broaden my knowledge and religious horizons.
"I'm an open mind, an open book. I want to learn about different faiths, cultures and religions and develop a firm understanding of my faith and how it can potentially play a larger role in my life."
A start date for the new series of Pilgrimage is yet to be announced.
