Britney Spears’ Till The World Ends video has launched and plays on the belief held by some that the world will end on December 21 2012, when the ancient Mayan calendar runs out.

In Britney’s world, however, when the world ends, the party starts. The video features Brit dressed in leather jacket, underwear and fishnets rocking out in a basement party as the city above her is demolished.

Meteors crash to the earth and black clouds roll over the city as Britney’s mates hop down manholes to join in the party.

“Keep on dancing till the world ends,” sings Britney in her red catsuit as a crowd of sweaty, skimpily-clad dancers grind away.

Britney posted the Till The World Ends video on Youtube this morning, a day after releasing a 30-second teaser clip.

Till The World Ends was written by Ke$ha and a second video – a director’s cut with an even more apocalyptic theme – is in the pipeline.

Britney has been slammed for not having even co-writing credits on her new album, Femme Fatale. But today, songwriter Heather Bright, who wrote many of the songs, defended the singer on her blog, writing:

“Britney could have come to me, like all these other A-list artists, and said …

 “Hey, you wanna be on my album? I’m gonna need writing credit for that song AND part of your publishing even though I didn’t write anything! And then I’m gonna go on tour and gross $150 million in ticket sales and not give you any of that, even though I’m performing your song!”

She continued: “Britney’s one of the few artists I’ve worked with who didn’t try to take something that wasn’t hers. In my experience, from a business standpoint, her entire team is nothing less than a bonafide class act!”
