Pop superstar Madonna has quashed rumors she's leaving obscure Jewish sect Kabbalah over concerns for her finances and family relations. The Material Girl singer is reportedly fed up of the financial burden of championing the Jewish belief system, and also fears the teachings are compromising her relationship with husband Guy Ritchie and her children. One area of alleged contention is Christmas - which the family currently do not celebrate. Madonna would now reportedly prefer her kids not to be alienated from conventional customs. Adding weight to speculation of a religious rift, pals claim the singer is thinking of ditching Kabbalah's trademark bracelet. However, a spokeswoman for Madonna insists she has no plans to cut any strings. She says, "As far as I am aware, it is completely untrue."
