Blake Shelton & Fellow ‘Voice’ Coaches Go ‘Crazy’

Blake Shelton is looking for the next big voice in music, as the country superstar joins Maroon 5 frontman Adam Levine, Christina Aguilera and Cee Lo Green as coaches on the new reality competition show, 'The Voice.'

Each 'Voice' coach will pick singers to mentor during blind auditions, during which they'll only hear the competitors and not see them. The coach then forms his/her own team to compete for the rest of the show, with viewers casting votes on the final winner.

The whole premise of the show is that it should be the voice that makes the singing superstar, and not his or her looks. The coaches just happen to be blessed with both. Check them out singing together Cee-Lo's mega-hit, 'Crazy' (which he famously recorded in his duo, Gnarls Barkley), below.
