Will.I.Am: 'Cheryl Cole Was Wasted On TV'
The Black Eyed Peas star also defends his mentoring on The Voice...
He said: "There are artists that rehearse loads and then when they get on stage they forget to bring emotion, because you can't practise that. Then there are people that bring the raw emotion and make you forget about your day, escape.
"Those are the ones that we call iconic singers. It's effortless... So my coaching is, let's talk and see what you're doing this for. That gives the performer a different sensibility.
"Then when you step into a song, your perspective is changed."
All five of Will and Tom's acts performed last night in the first live show of the series, with both Jaz Ellington for Team Will and Ruth Brown for Team Tom raising the roof.
Tune in to BBC1 at 19.25pm to see which two contestants will be voted off The Voice.
