Will.I.Am: 'Bieber Is A Great Talent'
The Voice coach also opens up about fighting for Chezza after XF USA boot...
"With the incident that happened with Cheryl, I was like, 'Hey Simon, Cheryl asked me to manager her, I have to fight for her, but I hope it doesn't change how you view me as an artist'," he explained.
"It was just wrong what happened to her and I stuck my neck out to fight for her. But since then relationships have been mended."
He added: "I could have burned myself, but that didn't happen and hats off to Simon for that. It could have ended up bad but it ended up great."
In fact, Will praised SiCo for being cool about his joining Britney as a mentor on XF USA despite his job as a coach on rival UK show The Voice.
The Black Eyed Peas star even confessed: "If I wasn't doing The Voice, then yeah, I like The X Factor. It's a great show."
