Who Won Best Actress: Jennifer Lawrence

Best Actress went to 22-year-old Jennifer Lawrence, who beat out fellow nominees Jessica Chastain, Emmanuelle Riva, Quvenzhane Wallis, and Naomi Watts, for her role as a recovering sex addict and widow in Silver Linings Playbook. No surprise here; she has been a front-runner for the award all along, and her performance also won her this year's Best Actress at the Golden Globes. She was also nominated for Best Actress for 2010's Winter's Bone.
