Three more big names are added to the already star-studded line-up of this year's American Music Awards. Katy Perry, Justin Bieber and Ke$ha, all of whom are coincidentally up for Artist of the Year prize, are tapped as musical guests.
Newly-wed Perry and "Tik Tok" hitmaker Ke$ha get three nominations each, and teen idol Bieber receives four. They collide with each other in a bid to win Artist of the Year alongside two other multiple nominees Eminem and Lady GaGa.
Bieber feels honored for being signed to sing at the gig, saying "As a small-town kid from Canada, I never imagined that I would be nominated for AMAs, let alone be performing on the show." Ke$ha is also ecstatic about the upcoming show since it's her first time, and thus she promises to "cover America in glitter" when singing "We R Who We R".
2010 AMAs is going to take place on November 21 at the Nokia Theatre in L.A. with Rihanna expected to kick off the event. The other performers are Bon Jovi, Usher and Pink. In addition, Christina Aguilera will perform "Burlesque" number to "showcase moments" from the upcoming movie.
