Star playdates: Celebrity kids who are friends

It's one of the most famous playdates of all time — when Angelina Jolie took her six kids, Maddox, Pax, Zahara, Shiloh, Vivienne and Knox to play with Kingston and Zuma at Gwen Stefani's house in London, September 2011. The Jolie-Pitts were in town while Brad filmed scenes for World War Z. Turns out Brad's been friends with Gwen and her husband, Gavin Rossdale, for years, and now Angelina and Gwen are tight.

Among other stuff, the kids smothered finger paint on themselves (as you can see), and the ladies sent security guards for take-out from the local Wagamama noodle restaurant for dinner.
