The 37-year-old will be volunteering as part of the charity for 16 hours a month.
Talking of his reasons behind joining the team, he admitted it was not a “selfless act”, as he wanted his “life back”.
He explained to Vicky Pattison on her The Secret To podcast: “I have got f**k all else to do and I am sitting around. I’m feeling quite inadequate.
“They’re doing such an amazing thing. I said I am doing this, I got really carried away researching it.”
