Where did you get the info about her getting a license to do fan art? That's not the kind of things that publishers usually give licenses for.
found an artist using a well known title song from madonna and using the concept.. will this be a copyright violation

Copyright does not extend to titles themselves, but not sure if that exact logo (font and such) is trademarked. If it is, then it's more questionable, but it's possible the photo overall can get away with the parody protection.
Is she trying to sell anything? I feel like if you're just using the title of something for personal use and not making a profit you're not really infringing on any rights. If she's selling prints of her photo or something that might be an issue but if it's just for her fb page...
