Her new single may encourage us to get to work, but for her promotional tour for her upcoming album in London, Britney Spears was the one working a variety of sleek, elegant outfits -- a definite departure from her trademark look in the late '90s. The singer has come a long way since her beginnings, but lately, her soft blonde curls have become a staple hairstyle, and we love how they gave her all-black ensemble a carefree vibe. Spears, who rode through London on a double-decker bus, was also spotted out in an embellished blazer, a chic camel trench, and sophisticated noir separates. Could this be the singer's new look for the Britney Jean era? We hope so! Check out her transformation from fresh-faced newcomer to the reigning queen of pop in our gallery.
