Last night, viewers of The Voice finale not only got to discover that Jamaican powerhouse singer Tessanne Chin won season five, but there was a special treat: a performance of Lady Gaga's stupendous pop hit "Do What U Want." However, this performance had one twist. The guest vocalist was not R. Kelly, but none other than Christina Aguilera, who was previously rumored to have an intense dislike of Gaga.

Whatever drama these two divas may or may not have aside, the two powerhouse vocalists went full throttle for a super sensual performance. Gaga does her best Xtina impression on "Do What U Want" anyway, full of throaty vocals and plenty of growls, so hearing Aguilera herself also put her spin on the track is oddly fulfilling.

The two battled it out, trading off lines seamlessly, though Aguilera largely kept to accompanying vocals. As for the performance itself, Gaga rocked a silvery space age suit and Aguilera donned the same fabric in a high-slit dressed.

The two paraded around the stage, getting the star treatment as butlers handed them champagne and they lounged on a stunning day bed, holding hands. In the end, as if in some sort of truce, Gaga and Aguilera linked arms and took a sip of the bubbly before promptly smashing their glasses on the stage.

Divas, indeed.

Watch the powerhouse team up from The Voice below:

"Do What U Want" is the second single from Lady Gaga's third studio album ARTPOP. Meanwhile, Aguilera is one of four coaches on the NBC show The Voice.
