Carrie Fisher, the actress best known for playing Princess Leia Organa in the original Star Wars trilogy, has died. She was 60. A spokesperson for the Fisher family confirmed the actress died Tuesday morning at UCLA Medical Center, days after she suffered a heart attack while onboard a flight from London to Los Angeles. Fisher had reportedly been in the hospital’s intensive care unit for days following the heart attack. Her mother, actress Debbie Reynolds, said Sunday that she was in “stable condition” and thanked supporters for their well-wishes. Fisher had reportedly suffered a cardiac episode 15 minutes before her flight was set to land at LAX on Friday. An EMT administered CPR and the actress was taken to a hospital, where she had initially been listed in critical condition. A passenger on the airplane later told the Washington Post that Fisher appeared to have been “in a lot of distress” on the flight. The actress had been conducting a book tour for her recently released autobiography, The Princess Diarist. This is a developing story. Follow Daniel Nussbaum on Twitter: @dznussbaum
