Britney Spears was in black lace and spandex last week to film the video for her song "3." The first single off her upcoming album has most of you wanting to hit the dance floor, and it's also earned Britney another spot at the top of the Billboard 100 — she's actually the first artist in three years to have a single enter the chart at number one. We'll soon get to see the results of Brit's hard work on the set, and she even took to Twitter to say she can't wait until her fans can view the results. Britney's been spending lots of time at the dance studio when she isn't out with her guy Jason Trawick, so her legendary moves are sure to be in tip-top shape.
