Look who's expressing himself.
Madonna's younger brother, Christopher Ciccone, is penning a memoir about his famous sister set for release next month, publisher Simon & Schuster announced today.
"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 company said in a press release.
The publishing house has ordered a monster first printing of 350,000 copies of Life With My Sister, set to hit shelves July 15.
Madonna's publicist, Liz Rosenberg, said there would be no comment "at this time."
The book was cowritten by Wendy Leigh (whose oeuvre includes salacious bios of JFK Jr., Arnold Schwarzenegger, Liza Minnelli and Princess Grace) and will be released on the Simon Spotlight Entertainment imprint.
The company began telling retailers several months ago that it was readying a major celebrity tell-all but kept the identity of its subject a secret, asking booksellers to order blind.
No word yet on what exactly the younger Ciccone, a noted Miami-based designer, plans to dish about his famous sibling, with whom he's worked closely in the past.
He helped mount and direct two of Madonna's biggest world tours, 1990's Blonde Ambition and 1992's Girlie Show. Most recently, he popped up as a guest judge on season three of Bravo's Top Chef.
