The 47-year-old actress is reportedly undertaking a series of meetings with publishers in New York to sell the rights to the tome, her agent Luke Janklow has confirmed.
However, her representative had no further information on the project, including title or expected release date.
This is not the `Ghost` actress` first foray into the literary world.
Demi - who is married to Ashton Kutcher and has daughters Rumer, 21, Scout, 18, and Tallulah, 16, with ex-husband Bruce Willis - was one of many famous faces who recently contributed to`That`s What She Said: Women Reveal What Men Really Need To Know`, a book which offers dating tips to men trying to woo women.
In the book - which also features advice from Madonna and Cameron Diaz, among others - Demi wrote: "If you want to get our clothes off focus on what you`re giving, not on what you can get! You may be able to score once - but we can smell the stink of selfish desires a mile away and are not interested."
