"Kabbalah Center" is a POS cult which has as much to do with Judaism as "Scientology" has to do with science.
She celebrated her faith in Kaballah by getting a set of Hebrew characters tattooed on the back of her neck. Her extensive knowledge of her new faith, apparently, doesn't extend to the Jewish prohibition on tattoos. Nor to the proper way to read Hebrew letters: the tatto is backwards, and thus gibberish. Matching the tattoo she got earlier, which she thought was the Chinese symbol for 'mysterious' but was later whorified to learn actually translates as 'strange'.
During an interview about her album, she claimed to have been influenced by 'Eastern spiritual religions'. When asked if she was referring to Hinduism, she replied "What is that? Is that like kaballah?"
