Britney Spears’ Video For ‘Till The World Ends’ Debuts

The song, co-written by Ke$ha, is the second single off Britney Spears‘ new album, Femme Fatale.

Set on December 21, 2012, the video sees Britney and friends dancing and partying in an underground lair as the world falls down above her. Buildings topple, fires rage but Britney just keeps on dancing. There is a great bit at the end too where Britney emerges from a manhole.
