Keith Urban quit a gig down under (and by that we mean the Australian version of The Voice for 2013) and hasn't exactly specified why other than pointing out "other commitments."
Mr. Nicole Kidman explained in a statement: "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."
As per The Hollywood Reporter, it's speculated that he's in heavy negotaitions to come the next judge on American Idol. Although he would be joining a hit show here, the departure in Australia is a big loss since The Voice is a smash success and gets more than two million viewers per episode.
"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 Percival, Delta Goodrem, Joel Madden and Seal -- thank you for making it so much fun," he added.
