Madonna is trying to convert her rumoured boyfriend Jesus Luz to Kabbalah.

The singer has reportedly persuaded the 22-year-old Brazilian model - who was raised a Catholic - to rethink his faith, and Jesus is now considering turning to the mystical off-shoot of Judaism.

A source said "Jesus has taken a real interest in Kabbalah and has started making a few online enquiries into the faith. He joined an online Kabbalah group and is keen to become and active member. Madonna has also offered to take him to the Kabbalah centre in New York and he is exceedingly keen to take her up on that."

Jesus' parents are believed to be concerned about the power 50-year-old Madonna appears to have over their son.

The source added to Britain's Daily Mirror newspaper: "Jesus' family are very traditional and quite religious so this news is sure to come as something of a shock. But Jesus is totally taken with Madonna and is slightly in awe of her. Quite simply he can't get enough, and finds her utterly compelling and bewitching."

The pair - who recently appeared together in a steamy series of photos for W magazine - are believed to have been dating since meeting on the shoot last December.

Meanwhile, a nude photograph of the "Like a Virgin" singer, which appeared in Playboy magazine when she was 20, has been sold at auction for $37,500.

The full-frontal black and white image - for which Madonna may have earned as little $25 for the 1979 modelling session - was bought by an unnamed European collector on December 12.
