The American Music Awards always bring big names onto the red carpet, and this year was no exception. Pulling out all the stops were Jennifer Lopez in a beautiful black lace number, Selina Gomez, who showed up on the arm of boyfriend Justin Bieber looking like an old Hollywood starlet in a Giorgio Armani's liquid metal-esque silk dress. Katy Perry went from Geisha girl to space cadet with her duo of frocks, while Nicki Minaj went big and bold in a green puffball. Well, there's no point being boring, is there?
