Age: 18
The youngest-ever winner of American Idol, Sparks scored a Top 10 hit this year (for her duet with Chris Brown, "No Air") and performed for millions when she sang "The Star-Spangled Banner" at the Super Bowl. And she's not afraid to take a stand: At the MTV Video Music Awards in September, the former plus-size model spoke out against British comedian Russell Brand's jokes about purity rings.
