Angelina Jolie and Brad Pitt have made no secret of the fact that they wish to educate their adopted brood about different cultures, and as a result have hired a multi-racial team of nannies.

The Hollywood power-couple have three adopted children; six-year old Maddox from Cambodia; two-year old Zahara from Ethiopia and four-year old Pax from Vietnam. They also have two-year-old biological daughter Shiloh who was born in Nambia.

And Jolie, who is currently pregnant with twins, insists it's important they grow up in an ethnically diverse environment.

She tells Vanity Fair magazine: "We have ladies that work with us and they're also from different cultures and backgrounds.

"One lady's a Vietnamese teacher - wonderful. One is of Congolese descent from Belgium. Another is from the States and is really creative and does art programs."

The actress insists she and partner Pitt are hands-on and don't shirk from their parenting duties - but admits when their fifth and sixth babies are born, they may need extra hands: "We don't have anybody stay the night. We may have to adjust that when the next one (sic) comes."
