Britney Spears

Britney Spears cracked the top 50 on our list thanks to her huge year. She made her debut on The X Factor as a judge during the show's second season but decided not to return to the show for another round. Britney made headlines when she signed on for a residency at a Las Vegas casino, which will begin in the Fall. She also returned to the music world with a collaboration with Will.i.am for "Scream and Shout" and her new song "Ooh La La," which will appear on the Smurfs 2 soundtrack. While she split from fiancé Jason Trawick in January, she has found love again with new boyfriend David Lucado, whom she started to date in February.
