Britney Spears has unveiled the music video to her latest video, Till The World Ends.
Set on 21 December, 2012, – the day the Mayan calendar predicts the world will end - the four-minute production has a post-apocalyptic feel.
It sees meteorites plummeting to the Earth as the pop star and her party dance underground.
The Kesha-written track is the second single from Britney's seventh studio album, Femme Fatale.
