New photos from the set of The Hangover 2 have leaked online.  Unlike the previously released and fairly innocuous set photos of the guys going through an airport to Thailand (where the sequel is set), these new photos could be considered spoilers.  I won't say anything else so if you want to take a look, you can hit the jump.

The Hangover 2 stars Bradley Cooper, Ed Helms, Zach Galifianakis, Justin Bartha, Ken Jeong, Mike Tyson, Liam Neeson, and Jamie Chung.  It's slated to open on May 26, 2011.

We previously reported that Liam Neeson was playing a tattoo artist in the movie (and presumably the guy who gives Ed Helms the face tat).  However, in a recent interview with People, Neeson shot down that rumor and wouldn't talk about his role in the highly-anticipated sequel.  As for the chrome-domed Galifianakis, TMZ says that his character Alan shaves his head and becomes a monk.
