Will, Kylie Minogue, Ricky Wilson and Sir Tom Jones are all coaches for this year's third series.
Over the past seven weeks the four piece have been putting together their teams with twelve artists on each with the final blind audition episode airing last Saturday night.
The next stage is the battle rounds as the coaches will pitch their artists against one another in knockout battle rounds, ditching one hopeful in each pairing.
But deciding who got the axe was hard for the panel and Will found one particular battle almost impossible to call.
The Black Eyed Peas star ended up fleeing backstage to avoid making a choice, The Sun newspaper reports this morning.
Will apparently begged producers for help in choosing which singer would be going home and which would be making it through to the knockout round.
A show source told the tabloid: “Will was struggling to declare a winner and suddenly rushed off stage.”
The battle rounds begin airing this Saturday night on BBC One with a marathon 2 hour, 15 minute long show.
