Christina Aguilera, Cee Lo Green, Adam Levine, & Blake Shelton Perform "Crazy" On The Voice

The Voice judges Christina Aguilera, Cee Lo Green, Adam Levine, & Blake Shelton performed Cee Lo's Gnarls Barkley's "Crazy" during a special preview of their upcoming show. I'm legitimately shocked at how this incredibly diverse group of people managed to sound so good together! The Voice premieres this coming Tuesday @ 9/8c on NBC & I will be watching for sure!
