It is almost a quarter of a century since she first sang Like A Prayer.

But it seems the intervening years have done little to help Madonna decide exactly who she’s praying to.

For it appears the queen of re-invention may be on the verge of one of her most startling changes yet, after she revealed she was studying the Koran.

The 55-year-old was raised a Roman Catholic, but for the past 17 years she has been a devout follower of Kabbalah, a mystical offshoot of Judaism.

Now the singer, whose current partner is a Muslim, has begun investigating Islam.

She said: ‘I am building schools for girls in Islamic countries and studying the Koran.

‘I think it is important to study all the holy books.

‘As my friend Yaman always tells me, a good Muslim is a good Jew, and a good Jew is a good Christian, and so forth. I couldn’t agree more.

Madonna has followed Kabbalah since 1996. She famously  persuaded her former husband, British director Guy Ritchie, to attend Kabbalah services before they split in 2008. But she and her current partner Brahim Zaibat, 25, have reportedly argued about religion because of his Muslim faith.

Madonna is said to dilute her children’s orange juice with specially blessed Kabbalah water, and often wears white clothes because they attract ‘positive energy’.
