The performer roster for the upcoming 2011 [article id="1672323"]American Music Awards[/article] 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 [article id="1673064"]previously announced[/article] 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 [article id="1671742"]"Moves Like Jagger."[/article]
Last month, in a [article id="1672358"]nomination special[/article] 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 [article id="1652764"]"Firework" at last year's AMAs[/article].
