The American Music Awards are diversifying their performance schedule by adding Chris Brown, LMFAO and Marc Anthony to the lineup.

The annual awards show, set to air on ABC on Nov. 20, now boasts an impressive list of performers that includes previously-announced names Christina Aguilera, Justin Bieber, Mary J. Blige, Kelly Clarkson, Katy Perry, Pitbull and Maroon 5.

Brown is nominated for Favorite Soul/R&B Male Artist and Favorite Soul/R&B Album for 'F.A.M.E.' LMFAO are up for Favorite Pop-Rock Band. Anthony is a past nominee for Favorite Latin Artist but didn't make the cut this time around. He may end up performing with Pitbull, since the two scored a hit this year with 'Rain Over Me.'

Adele leads the pack with four nominations, but she won't be singing live because of her impending throat surgery. Fans can still vote for the awards at the show's website.
