A&E’s “Secrets of Playboy” series examines the “dark sides” and “hidden realities” from Hugh Hefner and the Playboy brand. Hundreds of former Playboy Bunnies, Playmates, ex-girlfriends, and employees have written an open letter denouncing A&E’s “Secrets of Playboy” and the recent allegations made against Hugh Hefner. In addition, several of the women who signed the letter also issued personal statements about the claims in the docuseries. Most of them were especially hard on Holly Madison, who appeared on “The Girls Next Door. She hasn’t commented on the letter. Meanwhile, “Secrets of Playboy” airs on Mondays on A&E.
