While Will.i.am has been confirmed to return and Sir Tom Jones is rumoured to join him, Jessie J definitely won't be a part of the new panel.
Jessie, who was a coach on the first two years of The Voice on BBC, said: "I want to get back to music and The Voice takes up a lot of time."
She told the Press Association: "I've loved doing it. I've done four series now - two in the UK, two in Australia.
"I'll always be a supporter of the show and I'd love to go on and sing but I have to get back to music and get back to touring because that's really who I am and what I do."
Jessie went on to defend the lack of success from artists on The Voice UK, pointing out it was "hard for all of us"
"It's not overnight success. I think it's really just who it is and how hard they work," she said. "I think when you're in people's living rooms every Saturday night, it's like they're a star.
"I mean I've haven't been around in the UK for a little while and you've got to work extra hard when you come back. I think it's the same for everyone.
"Songs have to be really great when you release them. Not expect, never presume, always work hard."
The Voice UK 2017 will air on ITV from January.
