Christina Aguilera and Cee Lo's 'Nasty' duet finds its way online: Hear it here

Christina Aguilera and Cee Lo Green aren’t just co-judges on the NBC reality show The Voice—they’re partners in song, too.

“Nasty,” a just-leaked song featuring the “F— You” singer and the Bionic woman, has found its way online; the sound quality isn’t great, but you can listen after the jump:

The track isn’t a brand-new jam—Cee Lo told Jimmy Fallon that it was originally intended for the soundtrack to Burlesque but was excised at the last minute.

The whole thing sounds like a mash-up of a lot of different Aguilera eras, including the horn-happy vibe of her 2006 album Back to Basics and the call-and-response raunch of her 2002 single “Dirrty.”

It’s currently unclear whether or not the track will actually be released officially, or if the rough version is all we’ll get to hear of it.
