Will.i.am quits The Voice U.K. - report

will.i.am has quit the U.K. version of The Voice after four years as a judge, according to a new report.

The Black Eyed Peas star has told TV bosses that he will not be returning for a fifth series when filming begins next month, reports Britain's Star on Sunday newspaper.

The show is already one judge down after it lost singer Rita Ora to rival reality show The X Factor, and a spokesman for The Voice has insisted line-up negotiations for the fifth series are still ongoing.

Jason Derulo is being tipped as the favourite to replace will.i.am as he recently revealed "There's some talk about me doing The Voice. It's a cool show, there's interest from both parties, myself and them."
