First look: Britney Spears releases post-apocalyptic video for 'Till The World Ends'

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.
