EntertainmentTeen Takeover! The Year's Hottest (and Youngest) Stars

HAYLEY WILLIAMS

Age: 19
The flame-haired, pint-sized teen kicked off her year at the Grammy Awards, where her band Paramore was nominated for best new artist. While their album, Riot! was certified platinum, the group set gossip blogs in motion after they canceled a tour due to "personal issues" – rumored to be frustration on the increased focus on Williams. But like No Doubt, who famously dealt with a beloved, iconic frontwoman before them, Paramore rebounded and began work on a new album, due next year.
