The legendary actor best known for her many collaborations with Woody Allen, as well as films including Reds, The First Wives Club and Book Club, has died

Diane Keaton, one of the best-loved film stars of the past 50 years, has died at the age of 79 in California.

The news was confirmed by People magazine. Further details are not available at this time and her loved ones have asked for privacy, according to a family spokesperson.

Keaton’s death came as a shock across Hollywood and the rest of the world. The actor had not been in the public eye for some months, but no illness had been announced.

An enduring and singular icon of cinema since her Oscar-winning turn in 1977’s Annie Hall – which her director, writer, co-star and former boyfriend Woody Allen based heavily on her own life – Keaton starred in some of the key movies of the last half century.
