The day after winning Best Actress for her role in Silver Linings Playbook, Lawrence, 22, was right back at work – emerging from a Beverly Hills salon with newly dyed black hair as she prepares to play Katniss Everdeen in reshoots for the next Hunger Games movie.
The actress was dressed mostly in black, too – with a black cardigan and black skirt to go along with a gray T-shirt.
It was quite a contrast to her dazzling look on Sunday, with her golden hair and Dior Haute Couture dress with Chopard jewels, a Roger Vivier clutch and Brian Atwood shoes.
One thing she was still sporting, though, was her glowing smile.
Reshoots for The Hunger Games: Catching Fire are expected to begin as soon as this week, reportedly in Hawaii. The movie is due in theaters at Thanksgiving.
