Cher's daughter Chastity Bono is writing her memoir to document her sex change from a woman to a man.
The pop superstar's child, now known as Chaz, began the lengthy gender reassignment process last year (08) and now prefers to be referred to as a 'he'.
News of actress/writer Bono's sex change surgery was revealed in June (09) - and now he is set to cash in on his story after selling the rights to his autobiography to publishing house Dutton.
According to TMZ.com, Bono - who announced he is gay in 1995 - received "a handsome, six-figure deal" for the book.
The tentatively titled Coming Clean will hit stores in 2011.
