35. Britney Spears
Britney Spears had a stable year of happiness at home with her sons, Jayden James and Sean Preston. Her boyfriend, Jason Trawick, brought balance to things as well, though their relationship was subject to both engagement and breakup rumors. Britney wrapped up a world tour supporting her Circus album and made some fun, sexy MTV Video Award promos with Russell Brand and took home the "Ultimate Choice Award" this year at the Teen Choice Awards. Brit also made a bikini appearance on Letterman's The Late Show with a unique top 10 list. She also continued to focus on modeling for Candie's and building up a record-setting Twitter following.
