I think the pyramid jacket is a lot more about the worshiping of money than it is a conscious endorsement of the Illuminati. It's just a neat looking design, which is why it was put on the money.
The Swastika used to represent luck and was a Native American symbol, and later it was usurped by the Nazis as a symbol of their power. Which is the truth? It's a matter of interpretation. It's only a neat looking design that could symbolize nearly anything. "Sometimes a cigar is just a cigar".
That was a jacket she wore for a movie.
As for religion, she practices Kabbalah, which comes from Judaism.
