Selena Gomez, Taylor Swift Light Up The Strip At Billboard Music Awards

Las Vegas rocked hard last night as the music industry's best and brightest convened at the MGM Grand Garden Arena for the 2013 Billboard Music Awards, and Sin City's anything-goes mentality certainly made its way into the stars' sartorial choices, as fashions ranged from show-girl-esque to emo rocker chick.

On the va-va-voom end of the spectrum was Selena Gomez, whose white Atelier Versace with fluorescent detailing called to mind a 21st century Carmen Miranda (sans the fruit salad headdress, of course). Meanwhile, BFF Taylor Swift—who was the big winner of the night with eight trophies—opted for something a bit glitzier: an electric blue Zuhair Murad long-sleeve mini-dress with peek-a-boo paneling just below the shoulders. And then there was Miley Cyrus, who not only dropped single details but continued to flaunt her punk side in a checkerboard Balmain jumpsuit. King me!
