Even though they have not always gotten along, Christopher Ciccone is still there for Madonna. The author has reached out to his estranged sister in the midst of her split from Guy Ritchie, whom he wrote about in his recent book, Life With My Sister Madonna. In an exclusive statement to In Touch, Christopher opens up about one of the biggest divorces in Hollywood. "In writing my memoirs, I have made a great many observations about myself and my sister Madonna," he says. "I will not be commenting on her divorce as that is a private matter between her and Guy Ritchie and would consider any commentary on my part dishonorable and disrespectful. I have expressed my heartfelt sadness to her and her family and offered my support should she need it." After seven-and-a-half years of marriage, Madonna and Guy announced they were separating on October 15.
