Madonna's brother is set to write a tell-all book about his famous sister

Madonna's brother is set to write a tell-all book about his famous sister.

Christopher Ciccone has signed a deal with publishers Simon and Schuster and
will be working with Wendy Leigh, who's responsible for writing biographies
on Liza Minnelli, Grace Kelly and Arnold Schwarzenegger.
'Living With My Sister Madonna' will chronicle Christopher's 47-year
relationship with the 'Material Girl' singer and will have an initial print
run of 350,000 copies.
Madonna - who no longer has a close relationship with Christopher - will not
be involved in the project.
Her spokesperson Liz Rosenberg said: "Madonna has not cooperated with any
biography about herself."
Christopher has worked with Madonna, 49, before.
