What She's Done:
She was one-fourth of the 'Sisterhood of the Traveling Pants,' and had arguably her first grown-up role this year in 'The Town,' in which she played Ben Affleck's drug-addicted ex-girlfriend. Still, this 23-year-old beauty is probably best known for her role as Serena Van Der Woodsen on the TV series 'Gossip Girl.'
Lively will play Ryan Reynolds's love interest in the highly anticipated 'Green Lantern' movie, which could turn this TV actress into a legitimate movie star.
Did You Know?
Her half-sister is actress Robyn Lively, star of the '80s cult hit 'Teen Witch.'
