Country singer Blake Shelton has been cast as the fourth judge and coach on NBC's singing competition show "The Voice." Shelton will be on a weekly panel with Christina Aguilera, Cee Lo Green and Adam Levine.
Shelton is among country music's most active television personalities. He will be the co-host of the upcoming Academy of Country Music Awards and was the host of the 2010 American Country Awards. In 2007, he was a judge on "Nashville Star" and a guest judge on NBC's "Clash of the Choirs."
After blind auditions, Shelton, Aguilera, Green and Levine will each select singers to mentor by bringing in songwriters, producers and friends to help out with the singers' music. Carson Daly is the show's host.
At the finale, each coach will have their top contestant compete for the grand prize of a recording contract and $100,000.
The series was created by John de Mol, who will executive-produce along with Mark Burnett and Audrey Morrissey.
