Where to begin? The good girl gone bad has lived a lifetime in the last few years, but there's no question that she's earned her rep as one of the baddest chicks in the game. We already loved her style, swagger, and Bajan lilt, so the leaked nude photos just cemented what we already knew: Shorty is a 10. So she's also #1.

DECADE ACHIEVEMENT: Winning a Grammy for "All of the Lights" and becoming the fastest solo artist in Billboard history to achieve twenty Hot 100 top ten singles, which was recently cemented with her infectious hit, "We Found Love."
