The Associated Press contacted Madonna's spokeswoman, Liz Rosenberg, for a comment on the book («Life With My Sister Madonna») on Madonna being written by Christopher Ciccone.

Liz Rosenberg said that Madonna and her brother Christopher are no longer close. This was rumoured for several years, and it's now official.

Liz had no initial comment on the book, but told that "Madonna has not cooperated with any biography about herself."
