Former Take That star Robbie is apparently in talks to join the show when it moves to ITV from BBC next year.
A source told the Daily Star: "X Factor have been courting Robbie for years but The Voice team think they have a better chance because their filming schedule is shorter, and it allows him to concentrate on other projects.
"They want to shake up the show's dynamics and Robbie ticks all the boxes in terms of personality and experience."
Currently judging on the show's fifth series is Ricky Wilson, Will.i.am, Paloma Faith and Boy George.
Next year will see the talent show at its new home on ITV in a three-year deal, which includes a spin-off show on ITV2 and a two-series contract for The Voice Kids.
Producers have already put out a call for any talented acts to visit Open Mic Nights around the UK early next year where talent scouts will be present.
