Imagine you're Mel Gibson. You're in a bit of hot water after some questionable outbursts of violent, sexist and/or racist behaviour, and you want to rehabilitate that old twinkly Mel image. Where do you turn to? The Hangover 2, of course.

Yes, Mel Gibson is reported to have a cameo appearance in the sequel to Todd Phillips' comedy hit - an interesting choice of guest roles, given the lack of political correctness from the cast the first time round.

Still, turning up as a tattoo artist in the film will boost the box office takings. And it'll give Gibson a chance to remind people that he has a sense of humour. Just hopefully not the kind of humour that involves beating up women and insulting religious groups.

Mel will film his part in two weeks time.
