The world is about to end and Britney decides to have a dance-athon. Well, at least in the visual for her latest music video. The singer gets hot and sweaty while getting down to the sounds of “Till The World Ends”, the new single taken from her Femme Fatale album. The clip is a definite improvement from “Hold It Against Me” and she appears to be dancing a tad bit more (although rumors are circulating she has a body double.) I’m also getting a “I’m A Slave For You” vibe, no? What are your thoughts on the video?
