WATCH: William Hung Returns for ‘American Idol’ Finale to Sing ‘She Bangs’

Co-Host Reunion.
'American Idol' is really pulling out all the stops for its series finale.

Arguably one of the most memorable American Idol contestants, William Hung returned to the reality TV singing competition to help celebrate the show’s finale.

Hung exploded onto the stage in a black and white frilly, silken tuxedo top and black dress pants to the strains of Ricky Martin’s “She Bangs.”

He joined the show’s longtime host, Ryan Seacrest, to sing and dance to the infectious rhythms of the chart-topping hit of 2000.

Certainly, it helped the show go out with a bang.
