Today’s “Page Six” reports that Madonna has dumped her longtime buddy, actress Debi Mazar, because she doesn’t believe in Kabbalah. “They are no longer best friends,” a Madonna source is reported as saying. “Debi is very hurt and confused, but Madonna has made up her mind. These women have been friends for 20 years and now, nothing.”

Debi Mazar, a total doll, was Madonna’s hair-and-makeup guru back in the early Eighties in New York when the bushy-browed Material Girl had no material and sang like William Hung. So we’re talking through thick and thin. (I’m pretty sure it was Mazar who thinned those thick eyebrows.) Madonna is so immersed in the religious cult that her new best friend is Britney Spears, a Kabbalah convert. Madge not only gives all of her time to the mystical offshoot of Judaism, but a great deal of her cash as well. It sounds like Kabbalah is giving Scientology a run for its money. And its celebrities. Kabbalah counts among its followers Demi Moore and Ashton Kutcher, Paris Hilton, Brittany Murphy, Gwyneth Paltrow, Mick Jagger, and that lovable scamp Courtney Love. Roseanne and Elizabeth Taylor have been seen wearing the Red String, a strand worn on the wrist that protects believers from the powerful negative force known as the Evil Eye, which is defined as the “unfriendly stares and unkind glares we sometimes get from those around us.” You mean, like from the fans?

Next to Kabbalah, Scientology seems positively grounded. Until that spaceship takes off, that is. I’m just saying.

Not only did all proceeds from Madonna’s children’s books go to the Kabbalah-inspired Spirituality for Kids Foundation, she also insists on drinking only the Center’s “blessed” bottled water (twice the price of regular bottled water) and donated $5 million to the Center in London. Now she’s gotten Richie to write a movie with Kabbalah themes. Insiders also say she’ll donate a chunk of change from her upcoming “Re-Invention Tour” to the Center. (Page Six)
