Madonna has opened a Kabbalah school for children in New York, called The Kabbalist Grammar School for Children, or The K School for short.

The school is due to open at the end of the year, and will teach students the beliefs of the mystical Jewish faith, to be incorporated into a normal school curriculum.

"The school has been a dream of Madonna’s for some time," a source said. "Education means a lot to her and she was keen to make the most of her money by leaving a lasting mark as well as helping kids."

"She has been really dedicated to putting money away to pay for the building and she’s delighted to finally own it," the source added. "The papers have been signed and the school will be opening its doors to the first class in December."
