“Coach” Shelton

Blake Shelton has been named the fourth and final coach for the upcoming NBC series, "The Voice".

He will join Christina Aguilera, Cee Lo Green and Adam Levine. The series will debut on April 26.

NBC says the four coaches will each select singers to mentor during the auditions. Once they have their teams, the coaches will bring in their personal songwriters, producers and high-powered friends to help their teams evolve. The winner of a recording contract and $100,000 will be decided by viewers.

Carson Daly will host the show.
