6. JENNIFER LAWRENCE
During the major awards season, this then-unknown 20-year-old actress became the biggest threat to Natalie Portman's expected glory. Lawrence's role as Ree in the independent drama Winter's Bone, nominated for Best Picture, shot her up into instant A-list status.
Since then, she played Mystique in the hit X:Men: First Class and recently landed the coveted role of Katniss Everdeen, the lead in the young adult series The Hunger Games, i.e. the likely successor to Twilight fame when it hits theaters next year. Think of Lawrence as the next Kristen Stewart, except, she's a gorgeous blonde, not socially awkward and doesn't have any pictures of her smoking pot available for public consumption online.
