Madonna's brother to release memoir

NEW YORK, June 11 (UPI) -- Christopher Ciccone, Madonna's younger brother, has written a book about his U.S. pop star sibling, which is set for release next month.

E! Online said Simon & Schuster announced Wednesday its plans to publish the volume July 15.

"Ciccone's extraordinary memoir is based on his life and 47 years of growing up with and working with his sister -- the most famous woman in the world," the publishing house said in a statement.

Madonna's longtime representative Liz Rosenberg told E! Online there would be no comment "at this time" regarding the publication of "Life With My Sister."
