Hunger Games star and all-around charmer Jennifer Lawrence is already a leader in the Celebrity Brunch League (fairly self-explanatory definition: the famous people you'd like to share pancakes with), but now she is a member of another elite organization: the Celebrity Avengers, that brave and CPR-savvy band of actors who go around saving innocent lives. J-Law's story is as follows: She was walking her dog in Santa Monica when a passerby suddenly collapsed on the ground. Lawrence and a fellow witness attempted to revive the woman, then called for help and waited until the paramedics arrived. There are pictures of the heroics and everything! Free mimosas for J-Law next time.
