Jennifer Lawrence fended off stiff competition from Emmanuelle Riva and Jessica Chastain to win Best Actress at the Oscars on Sunday evening (February 24, 2013). The Silver Linings Playbook star was the early favourite in the betting, though Amour actress Riva won plenty of support in the weeks leading up to the ceremony at the Dolby Theatre. She was also celebrating her birthday on Sunday.

Lawrence - who ticked off a few people at the Golden Globes, announcing "I bet Meryl" - looked visibly stunned as she made her way to the stage, though she slipped and fell in her huge Christian Dior dress. Someone from the audience rushed to her aid, though Lawrence managed to compose herself and make it on stage. The fall appeared to rock the first-time Oscar winner, who quickly rushed through her speech before being ushered backstage. Twitter buzzed into life after the unfortunate stumble, with one Oscar-viewer joking, "Jennifer Lawrence just lived her dream and her nightmare." The reviews aggregating website Rotten Tomatoes tweeted, "Jennifer Lawrence is Best Actress, and Worst Stair Climber at Oscars. But if anyone can brush it off, it's her. Congrats, tiny dancer."

Lawrence's award preceded Daniel Day-Lewis's win in the category of Best Actor. He is the only actor to win the award three times.
