Behold, a play date that will make a thousand social-climbing mommies seethe with envy: Angelina Jolie brought her brood to Gwen Stefani's London home today, for a play date and dinner. Looks like Kingston and Shiloh got into one of their moms' makeup kits?

In the future, we will refer to this play date as the Stefani-Jolie Accords, when the greatest babies of a generation came together to make a giant mess of their faces. Their nannies are expected to negotiate bath treaties later tonight. [Images via Bauer-Griffin]
