Angelina Jolie & Brad Pitt Host A Go-Kart Party For Maddox

Looks like Maddox Jolie-Pitt has the need for speed! Angelina Jolie and Brad Pitt's oldest son turned nine last week, and on Saturday (August 7) his parents hosted a birthday party for him and his friends at Go-Kart World in Los Angeles.

RadarOnline reports that Maddox was joined by siblings Pax, 6, Zahara, 5, and Shiloh, 4, and around two-dozen other children. "They stayed for about two hours," said a source who was at the event.

"Brad and Angie were very nice people and only asked other people there not take pictures," the source says.
