Best-selling author Jackie Collins died of breast cancer on Saturday in Los Angeles. She was 77.

“It is with tremendous sadness that we announce the death of our beautiful, dynamic and one-of-a-kind mother, Jackie Collins, who died of breast cancer today,” her family said in a statement.

“She lived a wonderfully full life and was adored by her family, friends and the millions of readers who she has been entertaining for over four decades,” the statement said. “She was a true inspiration, a trailblazer for women in fiction and a creative force. She will live on through her characters but we already miss her beyond words.”

According to People, she had been fighting a private battle with breast cancer after being diagnosed with stage 4 of the disease in 2009.

The English author of 40-plus years was best known for writing novels, 500 million copies of which have been sold worldwide, about glamorous Hollywood lifestyles. Her latest book, “The Santangelos,” hit bookstores in June.

She is survived by her daughters, Tracy, Tiffany and Rory; sister, Joan Collins — the actress best known for her role on “Dynasty” — brother, Bill; and six grandchildren.

Private memorial services will be held in her honor in the U.S. and the U.K. In lieu of flowers, the Collins ask that donations be sent to the Susan G. Komen Breast Cancer Organization and Penny Brohn Cancer Care.
