Madonna’s estranged brother Christopher Ciccone just did an interview with Out magazine and revealed a rather juicy story that wasn’t included in his book.

And when I say juicy, I literally mean juicy!

Ciccone talks about a night out on the town with Madonna and Demi Moore — and it involves Demi squirting breast milk at lesbians.

“Yeah — and she’s [Demi] 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. My friend Michelle called me the next morning and asked me, ‘How do I get breast milk out of my black dress?’ and I said ‘How the f*ck would I know? Call Demi.’ It was hysterical. There are no pictures of it but it actually happened. The lawyers didn’t think it was wise for me to print that — so there’s your juicy tidbit.”

I guess when you gotta squirt, you gotta squirt!

Boots Girl BFF Luke attended an event in West Hollywood last night with Christopher Ciccone, aka Madonna’s brother. “I spoke with Chris about my run in with Madonna a few years ago in Chicago…she slammed the door in my face when I asked her for an autograph,” Luke told us.

“You ain’t the first one to have a run in with her,” Chris responded.

Nothing like a good Madge-bashing session!

Self-proclaimed “first ever supermodel” Janice Dickinson was at the event to support Ciccone who she is good friends with. “Janice was cool. When I asked her for the photo she said OK right away,” Luke told us. “But when I asked her to sign his [Ciccone's] book and she said NO WAY.

“I quickly went through the bookstore looking for her books and had her sign them. She started yelling in excitement that she was signing her own book,” Luke added.

According to sources the bookstore ended up running out of Janice’s books, (even though it was supposed to be an event to promote Ciccone’s books!) so she jokingly yelled out to staff that they needed to order more!

That sounds like one heck of a night!
