Have you seen Beyoncé performing at the Billboard Music Awards yet? It's kinda amazing, to say the least. Switching from her skimpy on-stage outfit, Ms Knowles chose this ultra sleek Lanvin dress for the press room photos — proving that she can leave Sasha Fierce on stage and do grown up glamour as well as anyone. She teamed the long sleeved dress with silver peep-toe heels and a pair of statement making hoops, but take a closer look to check out the intricate brooch detailing and silver edged neckline. Sexy, non? We're giving Beyoncé a standing ovation, what about you?
