The Black Eyed Peas star is one of four musical coaches on the new BBC one music talent contest, which sees hopefuls take part in so-called "blind auditions".
Speaking about signing up for the show, Will said: "I did the show because there’s an opportunity to help somebody out like I was helped out. If I don’t try and make an artist bigger than me than why am I here?"
And discussing the twist on the typical talent show audition, Will added: "I think that's a beautiful way to go about it."
