Brooke Magnanti
Belle de Jour is the nom de plume of a person who claims to have been a London call girl or high class prostitute. Under this banner she maintains a wildly successful blog, Belle de Jour: diary of a london call girl which by 2006 had achieved selection by The Guardian as their blog of the year and has given rise to two books published in both the UK and US.
A television series based on the book is currently in development with Channel 4 in the UK.
The name recalls the Catherine Deneuve movie of the same name. It means "Daytime girl" in French and is also the name of a flower.
