But which lady hit the highest note on the red carpet during at one of music's biggest nights? Let's check out their looks...
British chanteuse Adele looked elegant in a black Burberry three-quarter sleeve frock with Art Deco neckline, black pumps and a voluminous retro hairdo. The singer was a big winner for her vocal skills and her stylish and unique look.
Meanwhile, Zoe Saldana showed up to present an award and effortlessly rocked the red carpet in a plunging black and gold Barbara Bui mini and fabulous snakeskin platform sandals.
As for Beyoncé, not only did the babylicious one drop her pregnancy bomb but she looked freakin' amazing doing it! We're crazy in love with her flowing orange Lanvin gown—that stood out in a sea of black dresses—bonus! Jay-Z's lady loves those skintight dresses a little too much sometimes, so it's refreshing to see B. change her style to accomodate her baby bump.
Also going for different look was Selena Gomez, doing Gothic chic in a black lace Julien Macdonald mullet dress with gold accessories. Way to keep it interesting, babe.
Katy Perry, however, was back to her self again, looking like a sexy cartoon character in a pink-and-blue Chinese-inspired ensemble courtesy of Versace to match her lavender hair.
And last but not least is Demi Lovato! OK, so her tan is a little overdone, but the embattled starlet looked hot and sexy in her plunging silver mini with matching heels and wavy locks. If she doesn't take best dressed, Dem's certainly most improved, right?
