1. RIHANNA

Every video Rihanna released this year shut down the Internet when it dropped. Her risqué outfits got just as much attention as her music, which is saying a lot, considering how many records she broke and set this year. Her latest chart-topper "We Found Love" brings her tally to eleven No. 1 singles, which puts her in a league with Elvis and The Beatles. She landed her first movie role in Battleship, which hits theaters next year. Simply put, 2011 reads like a long list of accomplishments for Rihanna and there's no question that she held our collective attention more than any other famous woman. Cheers to that.
