Carrie Fisher, the iconic actress who portrayed Princess Leia in the Star Wars series, died Tuesday following a massive heart attack last week. She was 60.

“It is with a very deep sadness that Billie Lourd confirms that her beloved mother Carrie Fisher passed away at 8:55 this morning,” Simon Halls, a spokesperson for Fisher’s family, released to People.

Fisher suffered a heart attack last week aboard a Los Angeles-bound flight 15 minutes prior to landing. A medic onboard performed CPR on the actress until paramedics arrived to take the actress to UCLA Medical Center, where she was placed on a ventilator.

The daughter of screen legend Debbie Reynolds and singer Eddie Fisher, the actress made her Broadway debut as a teenager in Irene, which starred her mother. After making her big screen debut in 1975’s Shampoo and briefly enrolling in London’s Central School of Speech and Drama and then St. Lawrence College, Fisher dropped out, at the age of 19, after landing the role of Princess Leia in George Lucas’ 1977 space epic Star Wars.
