The coaches had a disagreement on the third episode of the brand new fifth series, which saw Kaiser Chiefs frontman Ricky tell Black Eyed Peas star will that his comments "really annoys" him.
It all kicked off when none of the four coaches - will, Boy George, Paloma Faith and Ricky - turned for rocker Billy Black.
However, while giving feedback, will said that Ricky should've turned.
But Ricky was not impressed: "Why do you always do that? I never say 'you should have turned for them'. It just really annoys me."
Will hit back: "Don't get bent out of shape because of my opinion. He's doing rock, you do rock, and he probably came on the show thinking there was someone who was right for it. You don't have to turn for it but I have to give my opinion, I can't sit here and be fake."
Proving that he really is pretty annoyed, Ricky responded: "Everything I turn for I truly have to believe can win the show, I didn't believe that would win the show, that was my honest answer."
As Boy George attempted to make the atmosphere less tense, Ricky added: "I don't know what's going on in will's head, no-one does."
We wonder what's in store next week...
