(CNN) -- Actress Carrie Fisher, whose grit and wit made "Star Wars'" Princess Leia an iconic and beloved figure to millions of moviegoers, died Tuesday in Los Angeles. She was 60.
Her death was confirmed in a statement issued by the publicist for Billie Lourd, Fisher's daughter.
"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 said.
Fisher's death came four days after she suffered a cardiac event on a flight from London to Los Angeles, according to a source familiar with the situation.

'The family business'
The actress and advocate, who got her start in Hollywood as a seductive teen in the 1975 film "Shampoo," was the daughter of screen legend Debbie Reynolds and singer Eddie Fisher.
But her biggest break as an actress came just a few years after she dropped out of high school to appear alongside her mother on Broadway.
She beat out the likes of Jodie Foster and Amy Irving for the part of Leia in George Lucas' original 1977 "Star Wars." Her tough-as-nails princess was strong and independent -- and the role positioned Fisher in the decades that followed as something of a feminist icon.
The film became a blockbuster -- the Internet Movie Database ranks it as the fourth most-watched movie of all time, behind "Titanic," "E.T. the Extra-Terrestrial" and "The Wizard of Oz" -- and turned Fisher into an overnight star.
"I was trained in celebrity, so I did the only thing I knew," Fisher once told Rolling Stone. "I went into the family business."
Fisher went on to appear in 1980's "The Empire Strikes Back" and 1983's "Return of the Jedi." She drew almost as much attention for Leia's hair and wardrobe as she did for her performances in the movies. Her character wore her brown hair in two enormous swirly buns over her ears, and donned a revealing metal bikini as Jabba the Hutt's captive in "Return of the Jedi."

I'm deeply saddened at the news of Carrie's passing. She was a dear friend, whom I greatly respected and admired. The force is dark today!

Tributes poured out from her fellow members of the "Star Wars" universe.
"Carrie was one-of-a-kind...brilliant, original," "Star Wars" co-star Harrison Ford said in a statement. " Funny and emotionally fearless. She lived her life, bravely...My thoughts are with her daughter Billie, her Mother Debbie, her brother Todd, and her many friends. We will all miss her."
Co-star Mark Hamill tweeted: "No words #Devastated."
"I'm deeply saddened at the news of Carrie's passing. She was a dear friend, whom I greatly respected and admired. The force is dark today!" tweeted another co-star, Billy Dee Williams.
Actor Peter Mayhew, who played Chewbacca in the "Star Wars" movies, said, "There are no words for this loss. Carrie was the brightest light in every room she entered. I will miss her dearly."
Kathleen Kennedy, president of Lucas' production company, Lucasfilm, said Fisher "had an indomitable spirit, incredible wit, and a loving heart. Carrie also defined the female hero of our age over a generation ago. Her groundbreaking role as Princess Leia served as an inspiration of power and confidence for young girls everywhere. We will miss her dearly."
At last I know what I want for Christmas. The galaxy's beloved Princess, fully functional once more. And soon.

I thought I had got what I wanted under the tree. I didn't. In spite of so many thoughts and prayers from so many. I am very, very sad.

'Hurt my feelings'
Fisher became a star alongside Hamill and onscreen love interest Ford, with whom she eventually revealed she'd been romantically involved for a brief time while filming the first "Star Wars" movie.
Her sudden fame overwhelmed her at times.
"Forty-three years ago, George Lucas ruined my life," she wrote in her book, "Wishful Drinking." "And I mean that in the nicest possible way."
Fisher wrote about not loving the exposure that came with success -- or Leia's characteristic hairstyle, which she called "idiotic."
"I weighed about 105 at the time, but to be fair, I carried about fifty of those pounds in my face! So you know what a good idea would be? Give me a hairstyle that further widens my already wide face," she wrote with trademark sarcasm.
After "Star Wars" Fisher had memorable supporting roles as a vengeful ex in "The Blues Brothers" and as a supportive pal to Meg Ryan and Billy Crystal in "When Harry Met Sally." Meryl Streep played a Fisher-like character in "Postcards From the Edge," based on Fisher's own semi-autobiographical novel about life as a recovering addict.
She published multiple books, including a memoir, "The Princess Diarist." Fisher also was known around Hollywood as a script doctor, having worked on such films as "The Wedding Singer" and "Sister Act."
Nearly four decades after the first "Star Wars," the actress reprised her most iconic role in 2015's "Star Wars: The Force Awakens." She also was digitally recreated to appear briefly as a young Leia in the current "Star Wars" spinoff, "Rogue One."
Fisher fired back at fans who mocked her for having aged since her last appearance in a "Star Wars" movie, tweeting, "Please stop debating about whether OR not I aged well. Unfortunately it hurts all 3 of my feelings."
Most recently, Fisher was in London filming the latest season of Amazon's "Catastrophe" and promoting "The Princess Diarist."
I'm sitting in stunned silence learning of the death of #CarrieFisher. In what has been a particularly sad year this may be the hardest. RIP

Talked about struggles
Fisher spoke openly about her struggles with alcoholism and bipolar disorder. She also was an advocate for mental health awareness and treatment.
"There are a couple of reasons why I take comfort in being able to put all this in my own vernacular and present it to you," she wrote in "Wishful Drinking," after detailing her diagnosis and an overdose incident. "For one thing, because then I'm not completely alone with it. And for another, it gives me a sense of being in control of the craziness."
She also spoke knowingly about the life of a celebrity. In a 2009 interview with CNN, Fisher said she was reluctant to enter the entertainment business because she saw what it did to her parents.
"Their bright, white, hot star of celebrity was slowly dimming and fading and cooling. It scared me. I saw what it did to them. It hurt them," she said.
People mistake celebrity for acceptance or love and believe they can maintain some "fantastic level" of fame forever, but that isn't the case, she said. Seeing what the effect that reality had on her parents led her to believe that "celebrity is just obscurity biding its time," Fisher told CNN.
Carrie is in stable condition.If there is a change,we will share it. For all her fans & friends. I thank you for your prayers & good wishes. pic.twitter.com/isXJqqFEB6

Family says thanks
Fisher is survived by her daughter, "Scream Queens" actress Billie Lourd, whose father is talent agent Brian Lourd. Her mother, brother Todd Fisher, and half-sisters Tricia Leigh Fisher and Joely Fisher also survive her.
Fisher was married to singer-songwriter Paul Simon for less than a year from 1983-84.
Fisher's representative, Nicole Perez-Krueger, issued this statement from Billie Lourd: "She was loved by the world and she will be missed profoundly. Our entire family thanks you for your thoughts and prayers."
Debbie Reynolds posted on Facebook: "Thank you to everyone who has embraced the gifts and talents of my beloved and amazing daughter. I am grateful for your thoughts and prayers that are now guiding her to her next stop. Love Carries Mother"
Fisher's death is the latest devastating loss to the Hollywood community, which has seen a number of legends pass away in 2016.
She was, you could say, a force.
