Britney Spears just released the video for "Till the World Ends," her second single off her new album Femme Fatale. The four-minute pop clip features Brit's signature style—leotards with fishnets, a see-through sequined body stocking reminiscent of her "Toxic" look, and plenty of hair throws from left to right. She also suited up with a studded cropped Burberry motorcycle jacket while writhing on the dance floor. How "I'm A Slave 4 U" of her! See all her looks in the video above.
