Mariah Carey Medleys, Jennifer Lopez Lives It Up With Pitbull on ‘American Idol’ Finale [Videos]
Mimi elected to perform a medley of hits that included 'Vision of Love,' 'Make It Happen,' 'Hero,' 'We Belong Together' and her new single '#Beautiful,' among others, while Randy Jackson played guitar! Mimi was a vision in a white, mermaid-style dress. We think she may have been lip-syncing.
She was followed by the equally divalicious Lopez, who debuted her new single 'Live It Up,' with a little help from her pal Pitbull. It also sounded like a lip-synced performance, we hafta say. J. Lo sure did look extra sexy, though.
Psy also danced his butt off to 'Gentleman.' Few have the dancefloor skills, moves or techniques that Psy has.
