Brook Busey (born June 14, 1978), better known by the pen name Diablo Cody, is an American Academy Award-winning screenwriter, writer and blogger. First known for her candid chronicling of her year as a stripper in her Pussy Ranch blog and 2006 memoir, Candy Girl: A Year in The Life of an Unlikely Stripper, Cody won wider fame as the writer of the 2007 film Juno, for which she won the Academy Award for Best Original Screenplay.

A sitcom written by Cody, called The United States of Tara, based on an idea by Steven Spielberg, is currently in pilot stage at Showtime. She has several other scripts in the development stage at various studios.

Diablo Cody is originally from Chicago, Illinois and moved to Minnesota to live with her Internet boyfriend, Jonny (now her husband). While there she decided, on a whim, to take up stripping as a "hobby" of sorts. Meanwhile she was working in an ad agency and was not particularly fond of her job. Within a year she got a promotion at the ad agency which wore her ragged, and was something she did not particularly care for (it demanded organization, which is something she was not very good at). Eventually she quit her day job (with Jonny's blessings) and began stripping full time. During the course of about a year she went from "Amateur Night" (which was her first stripping experience) to a place she refers to in her book as Sheiks, then to Deja Vu, and so on. She then took up work as a phone sex operator before returning to stripping. Shortly thereafter she decided to quit stripping and she and Jonny married. They moved to what she refers to as "the 'burbs, and no one strips unless they're taking a bubble bath". Her step-daughter was the flower girl in the wedding and according to Diablo they are very happy.
