Brad Pitt, Angelina Jolie, and Maddox Jolie-Pitt sported head-to-toe camouflage and protective helmets to get down and dirty playing paintball in England on Sunday. The trio were at a paintball park in Surrey, UK, where Brad has been on location shooting World War Z. According to his parents, Maddox has always been fascinated by guns and this time he got to tote one around as he, Brad, and Angelina shot paint pellets at their opponents. Maddox even designed the machine gun necklace Angelina and Brad have worn. Angelina got particularly into the action, crouching down behind a tree with her gun in hand. On the way home, the trio stopped off at a local pub for dinner. The Jolie-Pitts have been in London while Brad works on his zombie movie. Most of the family outings involve all six of the kids, but only Maddox was big enough to get in on the paintball action with mom and dad. Angelina's oldest son was also one-on-one with her for a recent flying lesson. The whole crew was together, though, last week when Angelina brought her kids over to Gwen Stefani's house for a playdate with Kingston and Zuma.
