Usher and Adam Levine stepped away from their red chairs and hit the stage on Monday's first Live episode of "The Voice." The R&B superstar and pop hottie debuted a cover of Stevie Wonder's "Superstition." 

The maroon 5 frontman played guitar with the band while Ursher laid down his oh so smooth vocals. (sigh) 

The performance got a huge stamp of approval from their peers Shakira and Blake Shelton, who were spotted jamming from their seats.
