Christina Aguilera, who's been cracking the whip as a music coach on NBC’s “The Voice,” is generating buzz because of her own voice – an unreleased song she recorded with co-star Cee Lo Green.

The track, called “Nasty" and leaked on Twitter and YouTube, has gone viral, according to Entertainment web site PopEater.com.

The song has a Jazz and Blues feel to it, and highlights Aguilera’s soulful singing and edgy notes.

The studio collaboration was intended to be featured in Aguilera’s first film “Burlesque,” but the song never made the cut, PopEater.com reported.
