Will.i.am has quit the UK version of The Voice after four years as a judge, according to a new report. 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. Kylie Minogue, who previously worked as a judge on The Voice last year (14), is rumoured to be returning, while music veteran Sir Tom Jones is expected to retain his place on the panel alongside Kaiser Chiefs frontman Ricky Wilson.
