Jennifer Lawrence and castmates from The Hunger Games: Mockingjay Part 2 segued from their panel at Comic-Con to the nearby Conan at Comic-Con logoSpreckles Theatre for a Conan taping tonight. Lawrence, who apparently has been known to break out in song, decided to leave Katniss Everdeen behind and channel Cher with a rendition of the uber-diva’s late-’90s smash “Believe.” The Oscar-winning actress, who was in third grade when the song topped the charts, gets an attempt at some harmonious help from co-star Josh Hutcherson. Lawrence and her Mockingjay co-horts held court at Hall H earlier Thursday for what turned into a going-away bash for the four-film mega-franchise.
