Christina Aguilera and the Other ‘Voice’ Coaches Go Nuts Over ‘Crazy’ (Video)

NBC’s new singing competition teases the public with an insane musical collaboration

Things get a little crazy in the new preview for NBC’s upcoming singing competition “The Voice.” Actually, things get really “Crazy,” in a totally wonderful way.

The new teaser for the series (premiering April 26) features the show’s coaches –Christina Aguilera, Cee-Lo Green, Blake Shelton and Adam Levine — belting out the 2006 Gnarls Barkley hit “Crazy.” While Green might have more practice with the tune, given that he sang the original recording, there’s no denying that Aguilera and her cohorts deliver a first-rate version of the song.

Feel free to go a little “Crazy” yourself by watching the video.
