Hip Hop, R&B, pop, rock, and country music came together under one roof at the 40th anniversary of the American Music Awards at the Nokia Theatre in downtown L.A. on Sunday. Nicki Minaj was radiant in a yellow Monique Lhuillier gown, Kelly Rowland dazzled in a bejeweled dress, Jordin Sparks coupled up with boyfriend Jason Derulo, will.i.am showed off his one-of-a-kind style, and Ludacris linked with Breezy and Swizz Beatz. The trio will perform “Everyday Birthday” live for the first time at tonight’s show.
