"While we are very nomadic, we would like to have a base in Europe. More attention is paid here to what is going on in the world and it is easier to get to Africa and Asia from here," Pitt told XL Semanal, a weekly magazine.

"We want our children to have a broad vision of the world. Spain, Italy and France have lots of quality of life and that is healthy," he added.

Pitt, 43, and Jolie, 32, are parents to adopted Cambodian son Maddox, three-year-old Vietnamese son Pax, two-year-old Ethiopian daughter Zahara and 16-month-old biological daughter Shiloh.

The couple, who starred in 2005 hit movie Mr and Mrs Smith, would like to adopt more children.

"We still have not finished. We are very lucky to have the means to give someone an opportunity," Pitt said.

"But it is more than that. I can't imagine my life without our children. If someone is thinking of adopting, I couldn't encourage them more."

The Hollywood couple, along with their four children, moved recently from New York to Los Angeles.
