The host-free event allows its winners as well as performers to  be the stars.  Both nominees  and  winners  are determined by online voting.

This year, Adele leads the pack with four nominations. Right behind her are Katy Perry, Lady Gaga, Lil' Wayne, Rihanna, Taylor Swift and The Band Perry with three nominations each.

The nominees for the biggest category, 2011 Artist of the Year, include Adele, Katy Perry, Lady Gaga, Lil' Wayne and Taylor Swift.

At last year's AMAs, Justin Bieber made history -- becoming the youngest artist to take home the Artist of the Year title.

"The highly talented group that makes up this year's 2011 AMA nominees have dominated the charts, airwaves and pop culture all year long," said the show's executive producer, Orly Adelson, and Larry Klein, AMA producer, in a statement.

Other live performances will come from Maroon 5, Christina Aguilera, Jennifer Lopez, Mary J. Blige, Kelly Clarkson, Pitbull, Marc Anthony, LMFAO, Nicki Minaj and David Guetta.
