A documentary is under works which will expose the dark secrets of late American businessman Hugh Hefner. The Playboy magazine founder, who was known for his hedonistic lifestyle, lived in the Playboy Mansion with a number of different women, and the programme is set to give the public a behind-the-scenes look into the reality of Hefner's private life, reports femalefirst.co.uk.

"The show is being filmed at the moment. Producers are speaking to girls who lived in the mansion," Daily Star newspaper quoted Carla Howe, a former Playboy bunny, as saying. Howe explained that although she has heard plenty of unflattering stories about Hefner, who died in September last year, she never witnessed anything untoward herself.
