Brad Pitt had two special visitors, his sons Maddox and Pax Jolie-Pitt, on the set of World War Z in Malta Saturday. Pax looked superstylish in his skinny jeans while Brad Pitt was once again in his World War Z scarf, cargo pants, and navy shirt, which at this points seems to be his one and only outfit for the zombie film. The Jolie-Pitts may be missing out on the July 4 festivities stateside, but they're still getting in the spirit of Summer overseas. Angelina Jolie wore a wetsuit for a family trip to a local water park last Monday, and she was also spotted bringing the six kids out bowling later in the week.
