Brad Pitt entertained his children with empty pizza boxes at daughter Shiloh's first birthday party.

The "Ocean's Thirteen" star and Shiloh's mother Angelina Jolie threw a bash for their daughter in Prague on Sunday with her adopted brothers Maddox, five, Pax Thien, three, and two-year-old adopted sister Zahara.

A source told Us Weekly magazine: "One time, when the kids were bored, Brad had them all throwing empty pizza boxes as Frisbees. Obviously, Shiloh was too young to join in, but you could hear her laughing."

The family feasted on cookies and cake and decorated the party with 50 brightly colored balloons.

Angelina - who is in Prague filming new thriller "Wanted" - had to work in the morning, but was home by 2 p.m. to be with Shiloh on her birthday.

Meanwhile, it has been revealed that Brad and Angelina are to decorate their children's bedrooms according to their country of birth. The couple's four children were all born in different continents and the pair are set to revamp their rooms in homage to their roots.

A source said: "Brad and Angelina want to give the kids a strong sense of their own culture while growing up in America, so they never lose the link to their past."

Angelina adopted Maddox from a Cambodian orphanage in 2002, and Zahara from Ethiopia in 2005. The couple had Shiloh together a year ago, and Angelina adopted Pax Thien from Vietnam in March.
