Angelina Jolie and Brad Pitt are preparing to celebrate Christmas three times this winter, to include their adopted children's native traditions.

The superstar couple have two adopted kids - Cambodian-born Maddox, five and Zahara, one, from Ethiopia.

Jolie says: "Zahara's Christmas is January 8. With Maddox, it is the water festivals in Buddhism. We're getting into all that with them."

Jolie and Pitt also have a biological daughter called Shiloh Nouvel, born earlier this year.
