Video: Britney Spears Releases Dance Version of 'Till the World Ends'

Britney Spears released a new video for her hit song 'Till The World Ends' featuring more dance footage of the pop star.

Spears tweeted last week about the alternate video, writing, "Just saw the final cut of the dance version of the #TTWE video. Not sure which one I like best?"

The original video for the song features Spears at an apocalyptic underground rave while asteroids fall from the sky.

The dance version, however, cuts out all of the apocalyptic scenes and instead adds in extended dance clips. The new video release comes amid reports that she's been using dance doubles in her recent videos.
