As promised, pop sensation Britney Spears has released the dance version video for her latest single, 'Till The World Ends'. 

The main difference between this edition and the original cut is that it has removed all of the apocalyptic elements and focuses solely on Spears and her crew dancing in the underground bunker. This is a bold move and comes during an onslaught of criticism that suggests she perhaps she used a body double in the first version. 

Regardless of the speculation, this is a great edit and has an equally impressive impact showing more footage of the 'Hold It Against Me' star's much-talked about moves. Watch the dance version of 'Till The World Ends' here:
