Matt Damon posts a picture of his bare bum to Ben Affleck

Matt Damon and Ben Affleck have been taking digs at each other for the past two weeks – but it’s all for a good cause.

The best friends are trying to raise money for their two charities, East Congo Initiative and

While filming to promote the charities the two just couldn’t seem to get along – take a look, it’s so funny.

Ben has been using Matt’s absence on Twitter to his advantage and recruiting Jimmy Kimmel in his public roasting of poor Matt, posting tweets, such as: “Matt you there? Right. We will fax you”, “Matt is prob too scared to get on twitter because no one likes him” and our personal favourite: “We’ve printed out this tweet, placed in a suitcase that we’ll courier to Matt.”




Meanwhile, Matt Damon, not missing a beat in the spat, decided to fax Ben and Jimmy Kimmel a picture of his bare bum.

Boys, eh?
