UPDATE: Fisher's brother Todd told Variety that she is now in intensive care and that reports that she was in stable condition were "writing between the lines." The Associated Press reported earlier that, according to Todd Fisher, the actress was "out of emergency" and in stable condition. But Todd Fisher says his sister is not in stable condition. “She’s in the ICU and everybody’s praying for her,” he told Variety in a phone interview. “There’s nothing new from the doctors. There’s nothing new at all. … There’s no good news or bad news.”

We'll update this article with further developments as needed.

Actress Carrie Fisher, known to fans around the world as Princess Leia from the Star Wars film franchise, remains in a Los Angeles hospital at this time after suffering a heart attack on a plane. The Los Angeles Times reported Fisher was rushed by paramedics to a local hospital after her flight landed at LAX around noon Friday.

Fisher was on United Airlines Flight 935 from London to Los Angeles when she collapsed. A statement from the airline said medical personnel were waiting to meet the plane after getting reports that a passenger onboard was "unresponsive." TMZ says an EMT who happened to be a passenger on the plane apparently gave her CPR. According to the story in the Times, a witness who was on the plane with Fisher said she appeared to be in distress.

Tweets from two passengers on the flight, Anna Akana and Brad Gage, reveal what happened:

The 60-year-old Fisher has been on a book tour promoting The Princess Diarist, her latest book. The autobiography included the revelation from Fisher that she and co-star Harrison Ford had an affair while filming the original Star Wars. The famously outspoken Fisher has been enjoying a career resurgence thanks to her return to the blockbuster franchise that first made her famous.

After her appearance in The Force Awakens, Fisher's character, General Leia Organa, was expected to play a much more significant role in the next Star Wars movie, Episode VIII.  But aside from her Star Wars fame, Fisher carved out a lucrative career as a writer. Her openness about her struggles with substance abuse and growing up in Hollywood -- she was just 20 when she filmed A New Hope and is the daughter of show business legends Debbie Reynolds and Eddie Fisher -- was a frequent subject she tackled, most famously in the book Postcards From the Edge, which was later made into a movie starring Meryl Streep. 

As you can imagine, there has been an outpouring of support for the star on social media, especially from her former co-stars.

Peter Mayhew, who portrayed Chewbacca in the Star Wars saga, tweeted words of support as well:
