Jennifer Lawrence hopped on her cell phone after a workout in LA yesterday. The actress sported some Adidas by Stella McCartney workout gear for the session. Jennifer has been on the West Coast lately, hitting the gym, hanging out with friends, and visiting the nail salon, before she gears up to go back to work in the Fall. Catching Fire is set to start filming then, and Jennifer will reprise her role as Katniss Everdeen in the second installment in the Hunger Games series. There are also several new roles to fill in the movie, including Plutarch Heavensbee, who will be played by Philip Seymour Hoffman, and Finnick Odair. The casting rumors around the latter part have been heating up recently, with actors from Armie Hammer to Hunter Parrish being named as possibilities — tell us what you think about who should play Finnick.
