Ciccone's Fury At Madonna Grave Shoot 7/30/08

Madonna's estranged brother Christopher Ciccone was left horrified when his superstar sister took him to his mother's grave for a video shoot.

The Material Girl singer invited her sibling along when she recorded the spooky scene for her documentary, In Bed With Madonna, which was released in 1991.

And Ciccone confesses that the night left him emotionally scarred. He tells Britain's Closer magazine, "There aren't many things in my life that I consider sacred, but my sister crossed that line.

"And then the film crew wanted me to lie next to the grave with her. There was no f**king way I was going to do that. She didn't even realize it was an issue or a problem - but it left a very deep mark on me."
