'American Idol' Finale: Psy, Jennifer Lopez & Every Pop Star Ever Perform

FUSE TV - 'American Idol' Finale: Psy, Jennifer Lopez & Every Pop Star Ever Perform

Despite the 12th season of American Idol being overshadowed by catty judges and lackluster ratings, the finale was nothing short of a royal pop affair.

Not only did former Idol contestant Jennifer Hudson duet with champion Candice Glover, but a huge host of pop stars gave top-notch performances. 

To perform new singles, Psy brought an army of hip-shaking back-up dancers for "Gentleman" (above) while Jennifer Lopez and Pitbull presented a circus-inspired production for collab "Live It Up"—for which fellow diva Mariah Carey definitely did not even clap for. (C'mon Mimi.)

The Band Perry, Adam Lambert, Emeli Sande and (a bald) Jessie J performed with this season's contestants too. We've got the best performances here.
