If madam, Michelle Braun is to be believed, until recently, Hugh Hefner’s girlfriends weren’t just using the old man as their sugar daddy; most of them may have been doing a little work of their own on the side.

Michelle, who used to run the high-class escort agency Nici’s Girls, is currently writing a tell-all book where she claims that she spent years whoring out the Playboy girls for as much as $10,000 per night. Some of her clients supposedly included two kings, several famous athletes, and a well-known TV personality. Michelle claims that at one point, as many as eight women living in the mansion were working as call girls.

Michelle was arrested and charged for money laundering after she was caught operating her call girl business online under the cover of a travel and security business. She pleaded guilty earlier this year, and was sentenced to three years probation. Her new book is expected to be ready for publish around the new year.
