Olympia Dukakis has died.

The American actress - best known for her roles as Clairee Belcher in Steel Magnolias and Rose Castorini in Moonstruck - passed away on Saturday at the age of 89, her brother has told.

Olympia‘s brother Apollo Dukakis took to Facebook to share that his sister died "after months of failing health."

He penned on the social media site: “My beloved sister, Olympia Dukakis, passed away this morning in New York City. After many months of failing health she is finally at peace and with her Louis.”

The announcement was illustrated with a photo that showed Olympia smiling.

Below the post, several of Olympia's fans shared their upset at learning that the talented star - who acted in over 130 stage productions, over 60 films, and in 50 television series - was gone.

One devoted fan typed: "Our deepest condolences to you and your family. We are so fortunate to have been witness to her brilliant work. The talent and devotion that your family represents is an inspiration to all."
