29. Kimberly Perry
This budding diva had a huge breakout year in 2011 as the guitarist and voice of rising country trio The Band Perry (along with her brothers). She got in the pop culture door with her aching crossover ballad “If I Die Young,” which drove the band’s debut album to platinum status, and stamped her presence with a series of dazzling showings on award-show red carpets. The button-cute blonde and her bandmates are prepping their second full-length for release later this year.—Jeff Royer
