Matt Damon might have failed at landing a Best Actor Oscar this year, but he has managed to make his way onto 'Jimmy Kimmel Live' finally with the help from his best friend Ben Affleck. Of course, his stay was very brief as Kimmel was soon able to kick him off, but it was enough to please the audience.

As part of the post-Oscars show, Ben Affleck arrived onto the stage of 'Jimmy Kimmel Live', nonchalantly wearing a massively bulging overcoat and claiming that finishing training for his Batman role has meant that all his muscle has turned to fat. In response to Kimmel's comment that he's 'ballooned', Affleck quipped: 'I didn't think this was going to be about body-shaming tonight'. But Kimmel was not to be fooled by the absurd moving bump and immediately got up to see what Affleck was hiding. It turned out to be a very red-faced Matt Damon, panting a little from the lack of oxygen, who unstraps himself from a body harness that Affleck is wearing and garners huge applause from the audience, to Kimmel's chagrin.

Affleck insists that it's time for the two to 'bury the hatchet', as Matt Damon finally seats himself in a guest armchair. 'This feels amazing!' He tells the audience, as Kimmel repeatedly inists, 'This is not a guest appearance!' He threatens to have the Damon arrested for trespassing and Affleck as an accessory, before agreeing that the segment can continue if the camera kept Damon out of shot. It doesn't exactly work out that way though and he's soon wheeled off the stage, still in his chair.

Kimmel and Damon have had a historic pretend feud going on, finishing each show for the last 12 years by apologising to the A-lister for being to pushed for time to include him in the show, and from there it has spiralled. Last year, 'Jimmy Kimmel Live' even saw the pair go through a stint of couple's therapy, but it looks like it will be a long time before these guys can be friends. Nice try, Affleck!
