Revealing new Hangover 2 image surfaces

So far, details on The Hangover Part II have been extremely sparse, despite the fact that the sequel to the comedy mega-hit is due out in May.

The whole gang's back for the follow-up, which involves a holiday to Thailand, and, we're guessing here, a groggy morning after…

Collider have picked up on a new image that has arrived in Entertainment Weekly. It's fairly spoileriffic, so if you want to go into the movie cold, cover your eyes now.

The shot features Alan, Phil and Stu (Zach Galifianakis, Bradley Cooper and Ed Helms), and a monkey in a rather fetching Rolling Stones waistcoat.

Does this mean Doug (Justin Bartha), who's absent from the picture, has gone missing again?

The lads have clearly had a pretty insane night out, as Alan's had his head shaved and Stu has some facial art that would make Mike Tyson proud, though Bradley Cooper just seems to be taking the opportunity to show off his trademark abs...

The accommodation isn't looking quite a plush as the Las Vegas suite, though.

Part II has a very tough act to follow, but by the looks of this image, this could be another insanely-funny ride.

Expect another massive box-office haul…
