Stars celebrated like true rock stars at the 2012 Billboard Music Awards last night, and while performances by Alicia Keys and Stevie Wonder, Chris Brown, and a tribute to the late Whitney Houston captivated audiences, we were glued to the screen to see who would steal the show in fashion. 

Our favorite looks of the night include singer Monica in Roberto Cavalli, Usher in a vibrant blue suit, and many, many others. Click through the gallery to see who wore what on the White Carpet!
