UPDATE: Mel Gibson axed from 'The Hangover 2' after complaints from the cast.

Mel Gibson has been in Hollywood jail ever since the disastrous fallout from his relationship with ex-girlfriend Oksana Grigorieva went public, and now he's planning his great escape, starting with a cameo in 'The Hangover 2,' according to New York Post's Page Six. He'll reportedly be playing a tattoo artist.

"It's a done deal," a source told Page Six. "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."

The 'Hangover' sequel catalogs yet another disastrous vacation for Bradley Cooper, Ed Helms and Zach Galifianakis, which this time takes the boys to Thailand.
