Angelina Jolie spent the afternoon out exploring Berlin with her kids today, including a stop by a coffee house in Tiergarten and a visit to the Bauhaus Archive museum. The Jolie-Pitts are taking advantage of their time overseas during Brad Pitt's promotional tour for World War Z. They've already visited London and Paris, and Brad and Angelina made their latest red carpet appearance in Berlin yesterday. It was an extraspecial event since it was also Angelina's 38th birthday. She celebrated after the event at dinner with her whole family, including Brad, Maddox, Pax, Zahara, Shiloh, Vivienne, and Knox. The group of eight will continue their travels in the run-up to Brad's zombie movie's June 21 release.
