Madonna the maternal girl

Madonna says she wants to have another baby with film director husband Guy Ritchie.

The 46-year-old pop star, children's author and mother-of-two said she and Ritchie were going to "see what happens".

But raising children is a worrying struggle, she told People magazine.

Asked if she was trying to get pregnant, Madonna said: "I'm going to have fun with my husband and see what happens."

But she added: "I worry about everything: if I'm exposing my children to the right things, if I said the right thing in an interview, if I'm taking care of all the people I'm supposed to care for.

"I'm a worrywart. I'm really a lot like everybody else."

Madonna has an eight-year-old daughter, Lourdes, by former fitness trainer Carlos Leon, and a three-year-old son, Rocco, with Ritchie.
