Ashton Jones, Karen Rodriguez, Naima Adedapo, Thia Megia, Pia Toscano and Paul McDonald waltzed back onto the 'American Idol' stage tonight one last time, to open the show for the remaining seven with a rocking rendition of Pink's hit, 'So What.'

The group's melting pot of voices sounded great, and paired perfectly with their rock n' roll outfits -- giving the pop song an extra edge. The five ladies sported all-black leather outfits, and Mr. McDonald sparkled in a rocker black jacket with glittery red roses, though nothing could override their smash-up performance.

"You just made America think twice about their decision!" judge Steven Tyler -- and Aerosmith rocker -- told the group.

The live 'Idol' episode continues with the remaining Top 7 performing music of the 21st century.
