Katy delivers faux-military performance, Stefano sings his debut single, while Roger Taylor and Brian May make a return to the show with The Queen Extravaganza.
Katy Perry and Stefano Langone took the stage on "American Idol" before the contestants who made it to the top 5 were revealed. The West Coast pop singer delivered her latest hit single "Part of Me", while the seventh-place finisher on the "Idol" season 10 showcased his debut single "I'm On a Roll".
Katy reprised her character in "Part of Me" music video by channeling her inner soldier once again. Wearing a pair of camouflaged shorts, a tank top and a pair of fingerless gloves, the purple-haired singer descended on the stage using a rope. "Me and 12 strong chicks dance it out military-style," so she tweeted after performing.
Stefano was introduced by Ryan Seacrest along with another season 10 alum Casey Abrams. Wearing an all-black attire, he got some male dancers backing him up. "Had such an amazing time! #ImOnARoll hope everyone enjoyed as much as me! #muchlove," he greeted his fans on Twitter soon after leaving the stage.
Another guest that night was The Queen Extravaganza. The official Queen tribute band rocked the show by covering the rockers' classic smash hit "Somebody to Love". Roger Taylor and Brian May, who performed with the top 6 contestants the night before, came back to join them halfway through the set.
The night ended with the elimination of Elise Testone. Before leaving the competition, she took a final bow with a rendition of Led Zeppelin's classic "Whole Lotta Love".
