The performer roster for the upcoming 2011 American Music Awards continues to grow. The show, which airs on November 20 on ABC at 8 p.m. ET/PT, will feature performances from party starters LMFAO, Chris Brown and Marc Anthony. The three stars will join a previously announced group of performers that includes Justin Bieber, Katy Perry, Kelly Clarkson, Mary J. Blige, Christina Aguilera, Pitbull and Maroon 5. The host-free event will be broadcast live from the Nokia Theatre L.A. Live and be preceded by a one-hour red carpet ABC special at 7 p.m. The action will start even earlier with an online pre-show beginning at 5 p.m. EST hosted by former 'NSYNC member Lance Bass, with help from Michael Buckley, Estelle, Sarah Hyland, Audrina Patridge, Josh Sussman and Xzibit. Aguilera and Maroon 5 will hook up to play their current smash hit "Moves Like Jagger."
Last month, in a nomination special hosted by Pitbull and Nicki Minaj, it was revealed that Perry would head into the show as one of the night's most-nominated acts (along with fellow females Adele, Lady Gaga and Taylor Swift), up for Artist of the Year, Pop or Rock Music: Favorite Female Artist and Adult Contemporary Music: Favorite Artist. It's somewhat fitting, given not only the rather huge year she's had, but that she also delivered a full-throttle version of her hit "Firework" at last year's AMAs.
For the fifth year, American Music Award winners will be determined by online voting. Fans can support their favorites in all categories by heading over to AMAVote.com.
