It was quite the birthday bash for young Maddox Jolie-Pitt, who turned the big six-years-old on Sunday. Proud parents, Brad Pitt and Angelina Jolie, surprised Mad with a weekend full of partying. Life and Style Weekly has the exclusive pics of the military-themed festivities. Maddox looked like he was having the time of his life, riding around with Brad on ATVs and playing Capture the Flag with his pals. Even Angelina and Zahara dressed in camouflage! And what does the world's luckiest kid get as a gift for the big 6? A new dirt bike, leather jacket and helmet. He's just a chip off the Brad Pitt block, now, isn't he?
