You're referring to the popular book and film "The Devil Wears Prada" by Lauren Weisberger, which was later adapted into a movie starring Anne Hathaway and Meryl Streep.
However, I'm guessing you might be referring to the possibility of a sequel to the film or the book. Lauren Weisberger did write a sequel called "The Devil Wears Prada" was not directly followed by a sequel. But there was another book, "Revenge Wears Prada: The Devil Returns", released in 2013, 14 years after the first book.
