Madonna's Estranged Brother: 'Her Daughter Will Rebel and Contact Me'

Madonna's estranged brother Christopher Ciccone believes the pop superstar's daughter Lourdes will "rebel" by contacting him.

Ciccone -- who has penned a tell-all book about his famous sibling, Life with My Sister Madonna -- is not in contact with his sister's children -- Lourdes, 11, seven-year-old Rocco and two-year-old adopted son David Banda -- but is expecting Lourdes to get in touch when she is older.

He says, "I haven't seen them in quite some time. I have met Lourdes and Rocco, of course. I think when Lourdes is ready to rebel, she may call me."

Christopher, 47, does not believe his sister is set to divorce her film-director husband Guy Ritchie and claims the star will do whatever it takes to keep her family together.

He added to Britain's New! magazine, "I don't believe that they are in the process of getting divorced. They have a family and I believe they loved each other when they got married. I think they will do what they have to do to keep their marriage going."

Life with My Sister Madonna, released July 14, 2008, has reached No. 2 on the New York Times Best Seller List; No. 16 on amazon.com's bestseller list; and No. 26 on barnesandnoble.com's bestseller list.

In the book, Ciccone criticizes the Material Girl hitmaker's lifestyle, saying that she is a "control freak". He also criticizes Guy Ritchie, claiming the Snatch director's homophobic attitude has strained the openly gay Ciccone's relationship with his sister. He also criticizes Madonna's Kabbalah faith, saying that it has validated her negative behavior, and he claims that she has tried to blackmail him into joining the religion.

Ciccone recently said he enjoyed Madonna's reaction to the controversy the book garnered.

He said, "I will admit to a guilty pleasure in watching her squirm. (Releasing the book was like a) giant f**king orgasm. Therapy I already had; this was pure sex."
