Jennifer Lawrence may be the star of the massively popular Hunger Games franchise, but she also k**ws what it's like to fangirl over someone. The actress had a hard time controlling herself on Thursday when she ran Into Bill Murray backstage at Comic-Con in San Diego. Jennifer, who also made a memorable appearance at last year's Comic-Con, couldn't help but point and make hilarious faces While standing next to the actor after he showed up unexpectedly. She did, however, manage to pull herself together long e**ugh for one smiling photo.
