'American Idol' Season 11 best and worst moments

Jason Derulo took to the stage to perform his new single "Undefeated," which fans of "Idol" were able to have a hand in by voting for the lyrics. And despite it sounding exactly like a Coke commercial, it was nice to see Derulo sans neck brace and recovered from his accident. It was also a little scary - he did a few little dance moves and it made us very nervous. Don't over do it, Jason!
