LOS ANGELES, Dec. 23 (UPI) -- Star Wars icon Carrie Fisher was listed in stable condition late Friday after she suffered a massive heart attack on a transatlantic flight to Los Angeles, a relative said.

According to a report by TMZ, the 60-year-old actress went into cardiac arrest in the first-class cabin of the plane while en route from London to California.

An EMT who was a passenger in the back of the aircraft administered CPR to Fisher 15 minutes before the plane landed and she was transported to a nearby hospital.

The Los Angeles Times reported she was listed in critical condition upon arrival at the hospital. Fisher's brother reportedly said she was eventually stabilized.

United Airlines said in a statement that medical personnel met Flight 935 on arrival at Los Angeles International Airport after a passenger was found unresponsive.

"Our thoughts are with our customer at this time," the statement read.

The daughter of entertainers Debbie Reynolds and the late Eddie Fisher is also an author, who candidly writes about her battles with bipolar disorder and drug addiction, and frequently mines her memoirs for stage shows.The star has lately been on the promotion trail for her latest book The Princess Diarist.

In addition to appearing in five Star Wars blockbusters as Princess Leia, Fisher has also co-starred in the films Shampoo, The Blues Brothers, Hannah and Her Sisters, The 'Burbs, When Harry Met Sally... and Jay and Silent Bob Strike Back. She reportedly had been in London filming scenes for the sitcom Catastophe this week.
