The singer confirmed he will not return for a second season of the talent show, when it relaunches on the BBC's rival broadcaster next year.
George announced his departure from the coaching panel on Twitter, writing: "Not doing this season of The Voice on ITV but sending @iamwill my love. Watch this space for what I am up to! :)"
Black Eyed Peas singer Will has already announced he will still be on the panel next year, stating: "I’m delighted to be continuing ‘The Voice UK’ on ITV and being a voice of direction and guidance for the usual suspects, and I’m thrilled to add 'The Voice Kids' to the mix.
"I know ‘The Voice’ switched to ITV, but I’m not going to BREXIT 'The Voice UK'. I’m happy to make ITV my home now. I love the UK."
Kaiser Chiefs frontman Ricky has also confirmed he will not be taking up his spinning seat once again.
ITV poached 'The Voice' from the BBC last year, following a fierce bidding war.
It has previously been rumoured the broadcaster is hoping to secure original judge Tom Jones, who was controversially axed by the BBC last year.
