A lot of celebrities turn to spirituality, often as a gimmick as it gets them publicity. I know of two people who are involved with magick and one of them is high up in his order. He is a musician and is nowhere near becoming the next (Insert famous singer here).
Magick doesn't bring us things we want, it brings us the things we need and have the capability of bringing into our lives.
I believe Katy Perry was accused of being a witch due to her grammy performance....I've never seen a witch pole dance on a broom stick or anything to do with a symbol of a black horse. Yet tele-evangelists are apparently making a stink out of the whole matter. Apparently it is all to do with Satanism and the illuminati.
I think it was merely an attempt to be artistic.
