Kristen Stewart in 'The Twilight Saga: New Moon'
She's got the power: In New Moon, Kristen Stewart's Bella is torn between two impossible loves, a vampire and a werewolf. What's a mortal teenager to do? Thanks to this supernatural sequel to 2008's Twilight, the cute shy girl is back in vogue just when the pop culture landscape is cluttered with brassy Hannah Montana types. And give it up for Stewart: the 19-year-old strives to avoid the limelight, despite being linked to swoon-worthy co-star Robert Pattinson.
