Actress Farrah Fawcett is in critical condition in a Los Angeles hospital in her latest battle with cancer, friends tell Radar. The 62-year-old former Charlie's Angel, initially diagnosed in 2006, has undergone chemotherapy as well as recent stem cell treatment in Germany. Long-time love Ryan O'Neal and their son, Redmond, have been at her bedside since her admission to the hospital last week. (More Farrah Fawcett stories.)
