Jennifer Lawrence doesn't just rush to action on the big screen. The "Hunger Games" starlet was walking her dog outside her L.A. apartment complex Monday when she stumbled upon a young woman lying on her back on the lawn. According to X17, Lawrence raced over to help the young woman while someone nearby called the paramedics.

A photographer on the scene told the photo agency, "Jennifer ran outside her apartment when she heard a girl scream and immediately called 911. When the EMT arrived, she stayed to make sure everything was OK. She was really scared for the girl."

The Santa Monica Police Department told TMZ, "The young lady who collapsed was a juvenile and was part of a group that was together," adding that "alcohol may have played a role in the incident."

Lawrence, sporting a casual look in gray sweatpants and a black tank top, got on the ground to assist the woman and stayed by her side until paramedics arrived. It's unclear why the woman was in front of Lawrence's property, but paramedics treated the unidentified woman on the scene, and she was then cleared to leave.

Lawrence isn't the only celebrity who has played superhero recently: Patrick Dempsey came to the rescue a little less than two months ago, saving a teenager who crashed his car outside the "Grey's Anatomy" star's house.

Lawrence is gearing up to reprise her role as Katniss Everdeen in the "Hunger Games" sequel "Catching Fire," slated to hit theaters in November 2013.
