Spencer Matthews is to climb Mount Everest to search for the missing body of his brother Michael.
The former 'Made In Chelsea' star has teamed up with Disney Plus to make a documentary about his expedition to the world's highest peak looking for the remains of his late sibling who died during a descent down the mountain back in 1999 when he was just 22.
Spencer underwent therapy before taking on the ordeal, and said on his 'Big Fish' podcast: "It was important for me to get my head around the fact I might come face to face with my brother’s frozen body. I knew it was going to be a gut-wrenching and emotional journey."
Michael died shortly after becoming the youngest British climber to summit Mount Everest following in the footsteps of TV adventurer Bear Grylls who previously completed the challenge at the age of 23.
Bear later led an exhibition back up the mountain in a bid to recover Michael's body, but it was not successful.
Speaking at the Oxford Union, Bear explained: "We actually had an expedition on Everest to try to recover the body of the brother of a good friend, who climbed it the year after I was there but was never found.
"We really tried. We had the best team in the world."
Spencer previously opened up about the effect the tragedy had on his family in his 2013 book 'Confessions of a Chelsea Boy: The Autobiography'.
The TV star explained they had struggled to find peace and it was particularly hard on his elder brother James.
Spencer wrote: "His loss was devastating for the family and over time this became worse because the circumstances surrounding Michael's death have never been fully explained.
"James took the news badly. With just a year and a half between them, he and Mike were the closest of friends. The loss was heartbreaking for James."
He added: "We have not been able to say goodbye in person. We have nowhere to go to sit with him. He lives on with us in our minds only. On Mike's birthday James and I send mum and dad red roses for the age he would have been. I guess our family's way of dealing with losing Mike is to believe that he goes on with us."
