The Hangover boys — Bradley Cooper, Justin Bartha, Zach Galifianakis, and Ed Helms, to be exact — gathered together in LA this week to get to work filming The Hangover Part III.

Meanwhile, Phil (Cooper) is still going strong in his marriage, as the guys and their wives get together for what looks like a night out on the town.
