Carrie Fisher, Princess Leia in 'Star Wars,' Dead at 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, said in a statement 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 her to UCLA Medical Center, where she was placed on a ventilator.
