New Video: Britney Spears, 'Till The World Ends' DANCE Version

Last week, Britney Spears premiered the video for her second single off of Femme Fatale, "Till The World Ends." She promised a second "dance" version of the video was on the way, and woo hoo, today's the lucky day!

In the updated "Till The World Ends" video, gone is that pesky story line about the impending apocalypse raining down above that seedy underground dance club. (Doomsdays are such bummers!) The new Britney video is sweatier, dance-ier and Britney-er -- "Till The World Ends" features mostly solo close-ups of Brit, as well as many more dance sequences. Basically, you now have a lot more moves to practice in the mirror.
