As Young was in the middle of performing his ever present mega-hit “Fireflies,” Ke$ha and two of her band mates hopped on stage—decked out as, uh, fireflies—and proceeded to jiggle around behind him. That’s certainly one way to jazz up a song that even Owl City fans have probably had their fill of.
Was Adam in on the joke? It doesn’t look like it. He seemed amused, nonetheless. Catch Ke$ha pranking Owl City below.
