UPDATE: The actress is now in critical condition as she's been placed in an Intensive Care Unit.
Iconic Star Wars actress Carrie Fisher has suffered a massive heart attack.
Fisher, 60, was aboard an 11-hour flight from London to Los Angeles on Friday when she went into cardiac arrest. After the plane landed just after noon in California, Fisher was spotted being rushed to the hospital. The Los Angeles Times reports that Fisher is in critical condition.
An airport onlooker tells WHO he spotted emergency workers assisting Fisher after they got her off the plane.
“It was scary. There was a team of about six emergency workers pushing her out in a stretcher. She had an oxygen mask on and they were yelling at people to get out of the way as they pushed her through,” says the witness.
Actress Anna Akana claimed on Twitter that she witnessed Fisher’s health emergency, writing, “Don’t know how else to process this but Carrie Fisher stopped breathing on the flight home. Hope she’s gonna be OK.”
“So many thanks to the United flight crew who jumped into action, and the awesome doctor and nurse passengers who helped,” she added. “Feel weird even tweeting about it but I JUST finished her book and was fangirling out over seeing her dog Gary in person. Gah.”
Comedian Brad Gage wrote on the social media site that he was traveling with Akana, noting that Fisher was allegedly “taken off the plane by EMTs.” Akana responded that Fisher “wasn’t breathing for 10 minutes or so.”
The actress has been in London filming the U.K. sitcom Catastrophe. Costar and co-creator Sharon Horgan shared an image of the duo on Instagram last week, captioning the playful photo “me, General Leia and Kylo Ren’s hand on the set of #catastrophe3.
After news broke, former costars and friends took to social media to send their prayers and best wishes to the iconic star.
Fisher recently published a memoir, The Princess Diarist, about her time on the set of the iconic first Star Wars film.
She previously starred in an autobiographical one-woman show, Wishful Drinking, that was also turned into a book and HBO special. It details her past struggles with alcohol and drugs including LSD, pills and cocaine.
The actress shares one daughter, actress Billie Lourd, with ex Bryan Lourd.
