Academy Award-winning actor Mel Gibson will be appearing in "The Hangover 2," media reported Tuesday.

The troubled actor "will make a cameo as a tattoo artist." Filming is taking place on the Warner Bros. lot, where a Bangkok set has been built, and Mel is expected to film his role in two weeks.

"Then the production moves to Thailand at the end of October,” according to the New York Post.

Most of the storyline details are still under wraps, but there have been web reports about the guys taking a trip to Thailand to attend a bachelor party.

"It takes place in Bangkok and L.A.," director Todd Phillips recently told Empire magazine. "There's gonna be some f---ed-up surprises."
