Jennifer Lawrence, is that really you?

The Hunger Games star looked drop-dead gorgeous in a stunning blue Viktor & Rolf mini dress, Sergio Rossi heels, and Jack Vartanian jewelry, as she posed on the red carpet at the PCA's, before taking the stage to present an award with Liam Hemsworth.

The 21-year-old Oscar nom dyed her blonde hair red to play Katniss Everdeen in the upcoming Hunger Games flick, and we think the new hue definitely suits her!

Lawrence is nominated for Favorite Movie Superhero for her role as Mystique in X-Men: First Class, but unfortunately she lost out to Ryan Reynolds for his turn as Green Lantern.
