If you haven't already heard, Mel Gibson has officially signed on to appear in a sequel to The Hangover.

According to numerous online sources, Gibson's cameo will be along similar lines to Mike Tyson's in the original. He will apparently play a tattoo artist.

I wouldn't normally post a story regarding a cameo, but this one will obviously be hot news given the Lethal Weapon stars recent personal troubles. Todd Phillips is returning to direct, will the four main cast also coming back. Shooting is happening as I type (probably).
