Angelina Jolie rounded up her troops and left Gwen Stefani's London home yesterday evening following a massive playdate! Gwen's sons Zuma and Kingston were able to let loose with Angelina's children Knox, Vivienne, Shiloh, and Zahara. The gang apparently got into some paint, as Vivienne, Shiloh, and Kingston all showed the aftermath on their faces. They even messed around with Kingston's toy swords, going up to the house's windows to put on a show for photographers. Angelina and Gwen made sure the youngsters had dinner, and ordered takeout from Wagamama for everyone. Angelina brought her kids to Gwen's place during the afternoon when the sun was still up. Both the Jolie-Pitts and the Stefani-Rossdales are currently in the UK at the moment. Gwen and Gavin Rossdale spend a few months of each year at their British home, while Angelina and Brad Pitt are abroad as he wraps up work on World War Z.
