NEW YORK (Reuters) - Pop star Madonna's brother Christopher Ciccone has written a memoir called "Life With My Sister Madonna," to be published next month by Simon and Schuster.
"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," Simon and Schuster imprint Simon Spotlight Entertainment said.
Ciccone, one of Madonna's five siblings, wrote the book with Wendy Leigh. She has also written biographies of John F. Kennedy Jr, Britain's Prince Edward, Liza Minelli and ghost-written Zsa Zsa Gabor's autobiography.
Madonna's spokeswoman Liz Rosenberg had no comment.
Madonna, whose original name was Madonna Louise Ciccone, made her debut in 1982. Her first album, "Madonna," which included hits such as "Holiday," "Borderline" and "Lucky Star," helped her become one of the best-selling pop artists, with more than 200 million albums sold worldwide.
The book will be published on July 15, a month before Madonna celebrates her 50th birthday.
