The who's who in music -- like Justin Bieber, Selena Gomez, Adele, Demi Lovato and Jessie J, to name a few --  waltzed down the notorious black carpet on their way to the 2011 MTV Video Music Awards.

We can safely assume that there's no written dress code for the biggest music event of the year, given that the celebrity ensembles were all over the board. The Biebs even brought his pet snake, Justine, much to the dismay of his girlfriend, who hosted the VMA pre-show event and awkwardly interviewed the 'Baby' singer.

The 2011 MTV Video Music Awards black carpet is aptly named, because these days, red carpets are for regular folks ... Which, as we all know, the hottest music stars are not. Check out these photos of some of your favorite celebrities as they strutted down the black carpet at the 2011 VMAs.
