9. SELENA GOMEZ

The death threats from those struck with a severe case of Bieber fever against Selena Gomez are making her more popular than ever. Not only did the 18-year-old host the 2011 Much Music Awards, but she recently released her third album, When The Sun Goes Down, and her latest film, Monte Carlo (co-starring hotties Leighton Meester and Katie Cassidy) hits theaters today. But what's even more remarkable than her prolificness is that we actually really care now. Thanks to her and Bieber's PDA seen all over the world, we're getting familiar with another side of the former Disney princess; now, we have another reason to be embarrassingly jealous of a 17-year-old boy.
