Australian singer Helen Reddy has died aged 78 in America.
Her children - Traci Donat and Jordan Sommers - confirmed her death in a statement on the star's official Facebook page.
Helen, who was best-known for her hit I Am Woman, died in Los Angeles.
The trailblazing songstress and activist's life was recently crafted into the hit movie I Am Woman.
"It is with deep sadness that we announce the passing of our beloved mother, Helen Reddy, on the afternoon of September 29th 2020 in Los Angeles," the family wrote.
"She was a wonderful Mother, Grandmother and a truly formidable woman. Our hearts are broken. But we take comfort in the knowledge that her voice will live on forever."
Earlier, her son posted a picture with his mother captioned with three purple hearts.
Diagnosed with dementia five years ago, she had been living in a nursing home for retired Hollywood stars in LA.
She found fame after arriving in New York as a 24-year-old single mother with only $200 to her name.
Helen went on to become the world's top-selling female singer in 1973 and then again in 1974.
She won a Grammy for I Am Woman and it quickly turned her into a feminist icon.
The singer was also well-known for her hits Delta Dawn and Ain't No Way To Treat A Lady.
