Madonna is rumored to have a couple of tattoos, however none of these rumors are confirmed, in fact the only designs which have been spotted on her, are those featured in the "Die Another Day" music video.
In the video Madonna is seen with a Hebrew script tattoo on her right shoulder, including the letters "lamed", "alef" and "vav". These letters form one of the many names for God as written in the Kabbalah.
