With its hair-raising dub-step breakdowns and incredibly infectious hook, 'Till the World Ends' is a stylistic change-up for Britney. The video, directed by Ray Kay, features Spears in several post-apocalyptic get-ups, dancing her ass off as the world crumbles around her and her crew.
Britney beat out Katy Perry's cameo-crazy 'Last Friday Night (T.G.I.F.), Bruno Mars' 'Grenade,' Adele's 'Rolling in the Deep' and Pitbull's 'Give Me Everything' for the top honor. Way to go, gurl! Stay tuned for our continuing coverage of the 2011 VMAs!
