Keith Urban will not be returning as a mentor on the Australian version of The Voice in 2013, the country music superstar announced September 13.

"I've been so fortunate to have been a part of The Voice," Urban, 44, told Australia's Nine Network in a statement. "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."

In addition to Urban, celebrity mentors on the show included "Kiss From a Rose" singer Seal, 49, Australian pop star Delta Goodrem, 27, Good Charlotte rocker Joel Madden, 33. In its first season, Urban coached aspiring singer Darren Percival to a second place finish behind Seal's Karise Eden.

"To everyone who sang on the show, I thank you; you've inspired not just me, but countless others," Urban told Nine Network. "To everyone behind the scenes and to my on-camera family -- Darren, Delta, Joel and Seal -- thank you for making it so much fun."

Urban, who has two young daughters with wife Nicole Kidman, 45, is reportedly in the running to appear as a judge on the twelfth season of American Idol with Mariah Carey.
