Angelina Jolie and Maddox Jolie-Pitt arrived on a flight to LAX last night. She's traveling with her oldest child after a few busy weeks. Following a March trip to Africa, Angelina was in California before heading to NYC, where she was spotted with her two other sons, Knox and Pax. Then Angelina was off to London. All of the traveling was on behalf of her philanthropic work — she spoke with victims of wartime violence, attended the 2013 Women in the World Summit, and addressed an assembly of world leaders at a G8 gathering. This weekend, though, brings a change of pace for the Jolie-Pitt clan. Brad Pitt's taking on a more lighthearted assignment by attending tomorrow's MTV Movie Awards to both hand off the movie of the year golden popcorn and promote his film World War Z.
