Brad Paisley, Ne-Yo, Pitbull & Judges Perform on 'The Voice': Watch

On last night's final performance showdown on "The Voice," we saw X-tina and Beverly McClellan steal the show with their chill-inducing duet of Aguilera's "Beautiful" (which you can watch below).

But Tuesday's (June 28) "Voice" was also filled with star-studded appearances and performances -- just as a finale week episode should be. From Brad Paisley performing alongside Blake Shelton, to Ne-Yo and Pitbull killing it, watch all the performances below.

And naturally, it would not be a big "Voice" send-off without another gig from the all-star judges. The dynamic quartet took on Queen again, performing the band's collaboration with David Bowie, "Under Pressure." And yes, Christina steals the show yet again -- but Cee Lo manages to swag it out, hard.
