Angelina Jolie  walked hand in hand with Knox when she brought Pax and the twins Halloween  shopping in Australia on Saturday. The busy mom and actress has been stationed in Oz to work on her new directorial effort, Unbroken , bringing a war hero's story to the big screen. Angelina has been spending plenty of time with the kids between filming, and some of the little ones have been making trips to the UK to hang out with Brad Pitt , who has been filming Fury in England. Last week, Brad sat down with Ann Curry  to talk about 12 Years a Slave, and his new film, The Counselor, hit theaters this weekend. Although we haven't seen Angelina and Brad together in months, new rumors sparked up that the two got secretly married after Angelina started wearing  what looks like a wedding  band. See all the pictures from Angelina and the kids' time down under!
