PHOTOS: 2013 Billboard Music Awards Blue Carpet + List of Winners

Actress/singer Selena Gomez wowed in a white and neon Jetsons-esque Versace Spring 2013 Couture dress with a plunging neckline that slithers all the way down her chest to meet a high leg slit. Finished off with metallic open-toe heels and a messy low pony, Gomez looks a little hurried, but with a fun amount of edge for the young superstar.

The back of Selena Gomez's Versace Couture dress at the 2013 Billboard Music Awards has a complementing plunging back slit to match the front!

No matter who wins big at the 2013 Billboard Music Awards, looks like boyfriend Casper Smart is going home with the best trophy. Jennifer Lopez dropped jaws during her brief appearance on the blue carpet, having to rush into the show since she was one of the night's performers. In a plunging gold sequin gown with sheer bottom, matching gold pointed-toe heels and clutch, and a chic slicked back 'do, the 43-year-old star showed everyone on site how to do the carpet right!

Miley Cyrus had everyone double-taking at the Billboard Music Awards blue carpet. In a sparkly knit harlequin jumpsuit from Balmain's Spring 2013 Ready-To-Wear collection paired with simple black heels and her now-iconic platinum coif, Cyrus is a vision of boundary-pushing fashion!
