Madonna to be mum again?

Madonna is planning to become a mother again at the age of 46, according to friends.

The Material Girl is reportedly keen to have a second child with husband Guy Ritchie and has even visited doctors to find out if she can still conceive a little brother or sister for Lourdes, seven and Rocco, three.

A pal tells American news site the DAILY DISH, "She has it all planned out to a T. She began visiting her fertility doctor in Los Angeles in late March. Her tour was already planned for the summer, but Madonna wanted to undergo tests to find out if she would be able to get pregnant and carry a baby at her age."

But doctors gave her the all clear.

The report also claims Madonna has sought the advice and blessing of her Kabbalah leader Rabbi Yehuda Berg - who told her "that more kids would be a great thing for her spiritual growth", reports the Daily Dish.

In a recent interview, the singer admitted concern she may not be able to conceive again, explaining, "Because of my exercising and this, that and the other, I've kind of screwed up my cycle a bit."
