Christopher: (on his former friendship with actress Demi Moore) A certain kind of diva carries a gay man around like a handbag, like an accessory. And then once they find the right straight guy, they don't need a male companion any more. We went out and Demi was dancing up on me and humping me from behind. The one part that's not in the book is that she was lactating at the time and she was squirting breast milk at my lesbian friends. The lawyers didn't think it was wise for me to print that.
Christopher (on his sister, Madonna): I think, ultimately, she's a lonely person and, unfortunately, it, it truly is lonely at the top.
Christopher: Yeah, I mean I -not very many brothers find themselves on their knees in their sister's dressing room, wiping sweat off of her - off of her naked body. It's just - it was an odd situation, and it wasn't - you know, I couldn't really tell my friends and - but I wanted to be there for her, and I knew that she needed someone there that she could trust.
Christopher: Things tend to get very cultish in L.A. Even at the Kabbalah Center. The celebrity thing alters everything. When you start to see Britney Spears hanging around there, you know. So now I do my own thing. But if you remember, 'Everything I do, good and bad, affects me and the world around me,' if you stop to think about what you're doing just for a minute, you're practicing Kabbalah.
Christopher: I find no excuse for Madonna's grossly unfair treatment of me.
Christopher: My one direction in life is to remain being an artist and getting paid for being one.
Christopher (on his short-lived dance career): I stopped dancing when she [Madonna] started touring.
Christopher (on rumors Madonna helped him write his tell-all book about her): If she did, then she's doing the best acting job I've ever seen, no she didn't help, Whoever is doing it (making up the stories) is doing me a great favour. I appreciate it.
