Madonna’s brother, Christopher Ciccone, is making the publicity rounds to promote his new book, “Life With My Sister Madonna.” The book is said to shed some light on the recent rumors of marital problems between Madonna and husband Guy Ritchie, who are rumored to be headed toward divorce. In the book, Christopher reports that a “Kabbalah rabbi would regularly…mediate between them…I believe that Kabbalah is helping keep Guy and Madonna together.” Ciccone, who is openly gay and once was artistic director for Madonna’s tours as well as her interior designer, believes that he made Guy uncomfortable and that because of this, Madonna’s marriage to Guy ended Ciconne’s relationship with his sister.
