Britney Spears

No, Britney Spears wasn't kidding around about dancing "till the world ends."

The pop star debuted her new music video for the single "Till the World Ends," from her No. 1 album Femme Fatale, today on MTV's The Seven. The events in the video take place on December 21, 2012, a date when several cultures believe the world will end. But rather than worry about the giant fireballs coming from the sky and the subsequent infrastructure damage, Spears' primary concerns are finding some company and busting out some elaborate choreography.
