(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.

It was 1977 and she beat out the likes of Jodie Foster and Amy Irving for the part of Leia in George Lucas' "Star Wars." The tough-as-nails princess was strong and independent -- and the role positioned Fisher in the decades that followed as something of a feminist icon.

"I was trained in celebrity, so I did the only thing I knew," Fisher once told Rolling Stone. "I went into the family business."

"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."

Celebrity tributes

Tributes immediately flooded social media.

"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 her "Star Wars" co-star Billy Dee Williams.

Actor William Shatner, star of the "Star Trek" TV series, tweeted, "I'm deeply saddened to learn of the death of Carrie Fisher. I will miss our banterings. A wonderful talent & light has been extinguished.

Actor Joe Mantegna tweeted: "Carrie always made me smile to be around her. My heartfelt condolence to all her family."

Fisher wrote about not loving the exposure that came with the success -- or the 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.

'Hurt my feelings'

She became a star alongside Harrison Ford, with whom she eventually revealed she'd been romantically involved for a brief time while filming the first "Star Wars" movie.

Nearly four decades after the first "Star Wars," the actress reprised her most iconic role in 2015's "Star Wars: The Force Awakens."

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 of my feelings."

In the years between "Star Wars" gigs, Fisher published multiple books, including a memoir, "The Princess Diarist." She also was known around Hollywood as a script doctor, having worked on such films as "The Wedding Singer" and "Sister Act."

Talked about struggles

Fisher spoke openly about her struggles with alcoholism and bipolar disorder. She 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."

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 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.
