I think she has converted actually. In one of the shots for the one major photo-shoot she did for Unbreakable, there is a photo of her wearing what I think would be considered a stylish version of the burka. The headdress in the first photo looks a bit like a hijab (my confirmation bias may be clouding my vision however) but the face garment in the second image is definitely something akin to the Muslim religion, no? If I am wrong about either photo, I will apologize
