Madonna has paid tribute to her brother Christopher Ciccone, who died at the age of 63, describing that he was the closest person to her.

Her brother, who was a tour director for the pop star and danced in her early music videos including Lucky Star, died from cancer on Friday in Michigan, United States.

In a heartfelt post on Instagram, the 66-year-old singer wrote that their bond was hard to explain but it grew out of an understanding that they were different.

Madonna says society was going to give them a hard time for not following the status quo.

She says they took each other's hands and they danced through the madness of their childhood, in fact dance was a kind of superglue that held them together.

The singer explained that discovering dance in their small Midwestern town saved her and then it saved him too.
