Christina Aguilera is back to her 'Dirrty' self and this time she's getting down with Young Money rapper Nicki Minaj.

On her new song 'WooHoo,' Aguilera and Minaj pay tribute to oral love, channeling Missy Elliot over the repeated 'WooHoo' vocal sample, singing "You know you really wanna taste my/ You know you wanna get a peek, wanna see my/ You know you wanna put your lips where my hips are/ Kiss on my, all over my/ All the boys think it's cake when they taste my/ You don't even need a plate, just ya face ha."

Minaj then adds a catchy, Jamaican-inflected verse, boasting about the power of her "mm-mmm nani-nani," just in case you had any confusion as to the song's topic.

The Polow Da Don produced heater, which you can listen to here, will be on Aguilera's forthcoming album, 'Bionic,' hitting stores June 8.
