Bieber, Perry and Ke$ha to Rock the AMAs
Among the three, Bieber has the most nominations with four, while Perry and Ke$ha have three a piece. They're all vying for the all-important Artist of the Year category.
While there's no word on what song Baby Biebs will be rocking during his rookie AMA performance, he told the Associated Press: "As a small-town kid from Canada, I never imagined that I would be nominated for AMAs, let alone be performing on the show."
