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.
