With siblings like these, who needs enemies? Mind you, I firmly believe Madonna is quite the ruthless, mean, controlling bitch that he paints her out to be, but that's your sister, man! Plus, Michael Ciccione is clearly a sour divo. He's mad cause he's irrelevant and he's hurting for a buck, so he figured he'd cash in by throwing his sister under the bus via a scandalous tell-all book. Check out his appearance on "Good Morning America."
It's weird that he referred to her as a "Catholic" girl. I think Madonna shed any ties to Catholicism way back in the "Like a Prayer" days, so I don't see how that's relevant. Besides, she's a Kabbalahist now. The Pope means nothing to her.
