Jennifer Lawrence is the Best Actress winner at the 2013 Oscars.
Lawrence won the Academy Award for her role in "Silver Linings Playbook."
"This is nuts," said the famously unfiltered Lawrence while accepting Best Actress.
The 22-year-old star had been the expected choice for Best Actress in 2013. Lawrence received awards from the Hollywood Foreign Press Association (Golden Globes) and Screen Actors Guild, but failed to secure a trophy from BAFTA. That award went to "Amour" star Emmanuelle Riva, causing some to wonder if the 86-year-old actress would swoop in an win on Oscar night. The upset, however, failed to materialize.
Lawrence played Tiffany in "Silver Linings Playbook," a troubled widow who finds friendship and love with a bipolar former school teacher named Pat (Bradley Cooper, an Oscar nominee for Best Actor). This was Lawrence's second Oscar nomination in the last three years; she was previously nominated in the Best Actress category for "Winter's Bone" at the 2011 ceremony.
Lawrence's Best Actress win came at the expense of not just Riva, but also Jessica Chastain ("Zero Dark Thirty"), Quvenzhane Wallis ("Beasts of the Southern Wild") and Naomi Watts ("The Impossible"). Wallis, who is just 9, is the youngest Best Actress nominee in Oscar history.
Last year, Meryl Streep won Best Actress for "The Iron Lady."
