Carrie Fisher, the actress best known as Star Wars‘ Princess Leia Organa, has died after suffering a heart attack. She was 60.

Family spokesman Simon Halls released a statement to PEOPLE on behalf of Fisher’s daughter, Billie Lourd:

“It is with a very deep sadness that Billie Lourd confirms that her beloved mother Carrie Fisher passed away at 8:55 this morning,” reads the statement.

“She was loved by the world and she will be missed profoundly,” says Lourd. “Our entire family thanks you for your thoughts and prayers.”

Fisher was flying from London to Los Angeles on Friday, Dec. 23, when she went into cardiac arrest. Paramedics removed her from the flight and rushed her to a nearby hospital, where she was treated for a heart attack. She later died in the hospital.

The daughter of showbiz veteran Debbie Reynolds and entertainer Eddie Fisher, Fisher was brought up in the sometimes tumultuous world of film, theatre and television.

Just two years later, though, the bright lights of Hollywood drew her back, and Fisher made her film debut in the Warren Beatty-lead Shampoo.

Her role in Star Wars would follow in 1977 – the experience she recently detailed in memoir, The Princess Diarist. She was only 19 when the first installment of the beloved sci-fi franchise was filmed.

In addition to the second and third Star Wars films – and last year’s The Force Awakens – Fisher starred in 1980’s The Blues Brothers, The Man with One Red Shoe, Woody Allen’s Hannah and Her Sisters in 1986 and, later, When Harry Met Sally.
