Keith Urban has officially left Nine's The Voice.

In a statement released this today, Nine confirmed Urban will not be a coach on next year's version of the smash hit reality talent search.

"We were really happy to have Keith as part of the inaugural Voice crew and of course he will always remain part of The Voice family in Australia. We are currently in negotiations with super star musicians to fill the coaching roles in 2013," Michael Healy, Nine Network's Director of Television today said.

Urban is believed to have lined up a multi-million dollar role on American Idol.

His appearance on The Voice has finally cemented him as a superstar in Australia after a decade of success in the US.

"I've been so fortunate to have been a part of The Voice. And as much as I'd love to do it again, it's clear that the recording and promoting of a new album, a tour and other commitments, will keep me from being a part of the second season," Urband said in a statement.

"To everyone who sang on the show, I thank you, you've inspired not just me, but countless others. To everyone behind the scenes and to my on camera family Darren, Delta, Joel and Seal, thank you for making it so much fun. Keep watching Australia!"
