Jennifer Lawrence debuted two new looks for her appearance on The Late Show in NYC today. She arrived wearing a short black cutout dress by Raoul with Jimmy Choos and was later seen leaving the studio in a long-sleeve Prabal Gurung look and the same sexy heels. It's been a busy month of press for Jennifer as she gears up for this Friday's release of The Hunger Games. Her costars Liam Hemsworth and Josh Hutcherson have also been promoting the film, and the duo popped up in Toronto for a premiere yesterday. Liam was in the Big Apple this morning for a visit to GMA where he talked about prepping for the movie by cutting back on calories and shared his experience working with Jennifer. Jennifer will continue making the rounds this week with a stop by Late Night With Jimmy Fallon and an interview with Chelsea Handler.
