Madonna's Brother Christopher Ciccone Dead at Age 63 After Losing Battle With Cancer

Madonna's brother Christopher Ciccone has passed away at age 63.

According to his representative, the famous sibling lost his battle with cancer in Michigan on Friday, October 4, mere weeks after the pop star, 66, and Christopher lost their stepmother, Joan Ciccone, to the same illness.

Per his rep, Christopher’s "loving" spouse, hairstylist Ray Thacker, was “faithfully by his side” at the end of his life. Madonna has yet to make a statement on the tragic passing of her relative.

The Evita actress and the late artist had a rollercoaster relationship over the years. In 2008, Christopher penned a book titled Life With My Sister Madonna, where he claimed she outed him in a 1991 interview and had issues with her former husband Guy Ritchie.

Their feud allegedly imploded when Madonna had cameras follow her to their mother's grave for her 1991 documentary Truth or Dare. "I kept it inside but I thought to myself, ‘OK, there are no boundaries now.’ You know, my mother’s now become a side — a bit player in her life, life story, and it hurt me. And I — my, my opinion of her altered at that moment. I never said anything about it," he said in a 2008 interview with Good Morning America. "I think, ultimately, she’s a lonely person and, unfortunately, it, it truly is lonely at the top."

The "Material Girl" singer's representative, Liz Rosenberg, fired back at the accusations made in the tell-all, claiming in a statement, "I would have to assume she has come to terms with the fact that they do not have a close and loving relationship. And with the book coming out, I assume that will remove the chances of that ever happening."

Despite not being particularly close, the two family members seemed to have made amends. "As far as I’m concerned, we’re good. We are in contact with each other, although I haven’t seen her for a long time. We’re back to being a brother and sister. I don’t work for her, and it’s better this way," Christopher explained in a 2012 interview.

"I couldn’t be more proud of her. She is a force to be reckoned with. Does she have Barbra Streisand’s voice? No,” he said with subtle shade. "Can she dance like Martha Graham? Probably not. But the combination of her abilities has made her great, and left a huge legacy for her, and through her, for me. So yeah, God bless her."
