Christopher Ciccone reportedly passed away on Friday, October 4 after a long battle with cancer, as confirmed by The Hollywood Reporter. Born on November 22, 1960 in Bay City, Michigan, Ciccone was one of Madonna's younger siblings.THR notes that Ciccone "died peacefully surrounded by his husband, Ray Thacker, and other loved ones." TMZ reports that he passed away in Michigan, and recalls that Madonna had just lost another family member her stepmom, Joan Ciccone, at 81 years of age a few weeks ago on September 26, 2024.Best known for being a designer and an artist, Ciccone maintained a very high profile in the 1990s due to his work as a creative director for Madonna's Blond Ambition World Tour (1990) and The Girlie Show tour (1993) two very iconic eras for the pop star.Unfortunately, the two siblings had an eventual falling-out that led to Ciccone's bombshell book, Life With My Sister Madonna, published in 2008. In the book, Ciccone references a 1991 interview with Out's sister publication, The Advocate, in which Madonna "outed him."Ciccone wrote in the seventh chapter of the book:"In an apparent ploy to garner support for the [Truth or Dare documentary] by ingratiating herself with her gay fans, she says, 'My brother Christopher's gay, and he and I have always been the closest members of our family.'"Madonna's quote "outing" Ciccone continued:"It's funny. When he was really young, he was so beautiful and had girls all over him, more than any of my other brothers. I knew something was different, but it was not clear to me. I just thought, I know there are a lot of girls around, but I don't get that he has a girlfriend. He was like a girl-magnet. They all seemed incredibly fond of him and close to him in a way I hadn't seen men with women.""I'll tell you when I knew," Madonna's quote in the book went on. "After I met Christopher [Flynn], I brought my brother to my ballet class because he wanted to start studying dance. I just saw something between them. I can't even tell you exactly what, but then I thought, Oh, I get it. Oh, okay. He likes men too. It was an incredible revelation, but I didn't say anything to my brother yet. I'm not even sure he knew. He's two years younger than me. He was still a baby. I could just feel something."Ciccone described that he felt "incensed" at the time, and highlighted that Madonna was "outing [him] to the readers of The Advocate" as "the perfect promotional tool for the movie."By 2019, however, Ciccone told Radar Online that he eventually reconciled with Madonna. He explained:"We are at peace now and just spoke last week. I recently moved from Los Angeles back to Michigan, where my father and family own a vineyard and winery."Madonna hasn't shared an official statement about Christopher Ciccone's passing as of this writing.This story is still developing
