According to The Associated Press, Krantz died of natural causes Saturday afternoon at her home in Los Angeles' Bel-Air neighborhood, said one of her sons, producer Tony Krantz.

Before she published the racy "Scruples" at age 50 in 1978, Krantz wrote for women's magazines such as Cosmopolitan, McCall's and Ladies' Home Journal. She eventually wrote 10 novels that sold more than 80 million copies around the world, CNN reported. She also published a memoir, "Sex and Shopping: The Confessions of a Nice Jewish Girl," in 2001.

Several of Krantz's books, including "Scruples," "Princess Daisy" and "Mistral's Daughter," were adapted into television miniseries in the '80s and '90s. A remake of the "Scruples" miniseries was "still in the works" when she died, Tony Krantz told the AP.
