【Watch Fast & Furious 8 Online】

UPDATED 4:05 PM PT

Carrie Fisher suffered a heart attack on Watch Fast & Furious 8 Onlinea flight from London to Los Angeles, law enforcement officials said Friday afternoon. She was transported to a Los Angeles hospital while in critical condition, but she was later stabilized and taken "out of emergency," her brother Todd told the Associated Press.

The actress and author was aboard a United Airlines flight bound for Los Angeles International Airport when she went into what was initially described as "full cardiac arrest."

Fellow passengers tweeted that she had stopped breathing and that a doctor and nurse on board administered CPR.

She was later taken from the plane at LAX by emergency medical professionals at around midday local time, according to the reports. Calls and emails to Fisher's publicists were not immediately returned.

Fisher was heading home for the holidays from her book tour promoting The Princess Diarist, her personal journal from her time on the set of the original Star Wars.

The 60-year old Fisher has written and spoken frequently about her health problems. She struggled with alcoholism, depression, bipolar disorder and drug addiction for many years.
