As a side note: the author of that article is great. Anne Helen Petersen basically has a PhD in Hollywood celebrity culture and history, which is basically one of my dream careers. Her book Scandals of Classic Hollywood: Sex, Deviance, and Drama from the Golden Age of American Cinema is a really fun read on the studio system era of Hollywood.
Another good Old Hollywood book is Scandals of Classic Hollywood. Each chapter is devoted to a gossipy Classic Hollywood scandal.
