Madonna has put her boyfriend on a diet.

A source said: "It's very important to Madonna that anyone close to her does two things - follow her religion and her diet.

"Jesus is now having to eat organic salads, brown rice and fish. Occasionally she indulges with a slice of wheat-free wholegrain toast with sugar-free strawberry jam."

Madonna, 50, began encouraging Jesus to join Kabbalah, the mystical offshoot of Judaism she follows, soon after they started dating last December.

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."
