Heidi Fleiss (born December 30, 1965), known as the "Hollywood Madam," was convicted in connection with her prostitution ring that had numerous famous and wealthy clients, including Charlie Sheen. Her father, Doctor Paul M. Fleiss, also convicted in connection with the sex crimes of his daughter, is a famous Intactivist (one who believes in the right of children to genital integrity).

She was referenced in the song The Wrong Band by singer/songwriter Tori Amos: "I think it's perfectly clear we're in the wrong band/Heidi says she'll be sincere as much as she can/She called me up and she said 'You know that I'm drowning/It's the dog trainer again." Fleiss and Amos were friends in Los Angeles in the 1980s when Amos was a hair-metal singer.

In 2003 Fleiss accused her ex-boyfried, actor Tom Sizemore, of domestic violence and other threatening behavior. On August 15, 2003, Sizemore was convicted by a California jury of domestic violence, making criminal threats, and making obscene phone calls.
