Beyonce's Black Lanvin Billboard Awards Look

Beyonce Knowles at the 2011 Billboard Music Awards held in Las Vegas on May 22.

B opted for a black v-neck dress with a brooch adornment from the Fall 2011 collection of Lanvin.

Quite a simple look from Beyonce, and not a bad one, it's just this is Beyonce, we expect more. 

An extra touch of glitz came from her Christian Louboutin "Jenny" Knotted pumps ($895 at neimanmarcus.com) and huge silver-and-black Lorraine Schwartz earrings.
