It's official: the wolfpack is back.

No, we're not talking about Taylor Lautner and crew. This time it's "The Hangover" quartet – Bradley Cooper, Ed Helms, Justin Bartha and Zach Galifianakis. They were photographed at Ontario International Airport on Friday shooting scenes for the sequel, "The Hangover 2."

In the pics, which popped up on PopSugar, the boys are seen walking through the airport with terminal intensity. Galifianakis' Alan Garner, the black sheep of the pack, is hilariously overdressed in a four-pocket Allan Quatermain-esque white safari jacket and scarf. And yes, he does appear to have his satchel.

With passports in hand, the guys are geared-up for their Thailand adventure, but what sort of depraved shenanigans will they be up to in Bangkok? According to Latino Review, "after a hard night of partying Stu gets really drunk and ends up sleeping with a Thai tranny. The next day the guys have to try and rehash the night and figure out what happened."

While this is all scuttlebutt so far, you can be sure director Todd Phillips and the gang will be upping the ante as they get drunk and wild in the sex tourism capital of the world. The great Dr. Ken Jeong also will be returning as the gangster Leslie Chow.

"The Hangover 2," which began shooting in Los Angeles on Sept. 29 and moves to Thailand for the remainder of the shoot, is scheduled to trash multiplexes everywhere on July 4, 2011.
