98. Miley Cyrus
Miley Cyrus has been all about growing up and moving beyond her Hannah Montana image — she started with a controversial pole dancing performance at August's Teen Choice Awards. Her song "Party in the USA" was one of the biggest Summer anthems, and Miley also worked on her film career, scoring a cameo in Sex and the City 2 and the starring role in The Last Song. On that set, Miley met her current boyfriend, Liam Hemsworth. She once again proved that she's no longer a kid by debuting a tattoo and titling her newest track "Can't Be Tamed." It's her second year on the PopSugar 100.
