After a very tight race, Jennifer Lawrence won Best Actress for her performance in "Silver Linings Playbook."

It's the first Oscar for the 22-year-old Lawrence; even though she fell on the way up to the stage, she still managed to charm the audience with self-deprecation.

The other nominees were Emmanuelle Riva ("Amour"), Quvenzhane Wallis ("Beasts of the Southern Wild"), Jessica Chastain ("Zero Dark Thirty") and Naomi Watts ("The Impossible").
