If there's one woman in music who has truly hit rock bottom in the public eye, it's Britney Spears. In January 1999, the lovely Ms. Spears broke the pop music scene with her "Baby, One More Time" Catholic schoolgirl costume and dance moves to match. Although many Britney's seen many hits in her time, one that breaks from the pack is 2004's "Toxic," the video in which Britney shook her bootie down an airplane aisle as a sexy, futuristic stewardess. Her trajectory slowed as she ceased recording to get married and have her two children. Shortly after, Britney basically lost it, and shaved her head in a bargain salon in front of horrified hairstylists and, of course, paparazzi. But in the last month, she has proven that she will not be stirred - winning two moonmen at the MTV Video Music Awards, and releasing "Womanizer," currently the number one single. So gather some friends, and you can dress for Halloween as the evolution of Britney Spears! Check out my SLIDESHOW for some ideas!
