A source told the New York Post: "It's a done deal. Mel will make a cameo as a tattoo artist. Filming is taking place on the Warner Bros. lot, where a Bangkok set has been build, and Mel is expected to film his role in two weeks.

"Then the production movies to Thailand at the end of October," they added.

The popular “Hangover” cast members Bradley Cooper, Zack Galifianakis, Ed Helms, Justin Bartha and Ken Jeong are set to return for the sequel. However Heather Graham who played a stripper in the original film will not be making a re-appearance.

"Unfortunately Heather won't be in the sequel - the way the story unfolds doesn't allow any room for her character to show up. I don't want to reveal too much of the film, but once you see it you'll understand," explained a Warner Brothers representative.
