She's a hero in real life too, not just on the big screen! Yesterday the Hunger Games star rushed to the aid of a teenage girl, and helped her call 911. The girl collapsed on Jennifer's front lawn, and Jen called the paramedics right away, and waited with the girl until they arrived: "Jennifer ran outside her apartment when she heard a girl scream and immediately called 911", a source on the scene tells. "When the EMT arrived, she stayed to make sure everything was okay. She was really scared for the girl". The girl was treated on the scene and later taken home by a friend. Good job, Jen, such a heroic act! (x17)
