Stepping out in a metallic satin gown with a thigh-high slit, Selena Gomez looked glamorous as she strutted her stuff on the red carpet with her beau Justin Bieber. The Biebs kept it classic in a tuxedo and slicked back hairdo. Katy Perry looked fierce in purple pumps and a pink floor-length dress that played off of her hot pink locks. Taylor Swift look dazzling in a gold strapless number, while Jennifer Hudson looked super sexy in a silver mini dress and smooth, straight hair.
