Madonna's request for financial donations for the religious movement she fervently supports is causing friction between her and close pal Stella McCartney.
The Material Girl 45, has been criticised by the fashion designer for requesting huge financial gifts for the mystical Kabbalah movement.
A friend of former Beatle Paul McCartney's daughter says, "She doesn't see why she should pay huge sums just to follow the Kabbalah teachings."
McCartney was first introduced to the sect - an offshoot of Judaism - by Madonna over a year ago, and was intrigued enough to attend several meetings.
Her mother, the late Linda McCartney, was Jewish and friends say McCartney was "very open" to joining the alternative religion.
The source adds, "She simply doesn't believe that she should pay through the nose to worship something she believes in."
