Ben Affleck smuggles Matt Damon into Jimmy Kimmel's post-Oscars special…reignites 'feud'

Ben Affleck looked more like Willy Wonka's blown-up Violet Beauregard than Batman during Jimmy Kimmel's post-Oscars special.

The actor, who appeared on the show to promote Batman v Superman: Dawn of Justice, showed up looking noticeably more rotund than usual in an oversized coat, raising suspicion from the talk show host.

Watch the clip above to see Ben, 43, forced to reveal that he's hiding Jimmy's arch nemesis Matt Damon under his bulk.

Matt, 45, and Jimmy have had a faux feud for over seven years now that began when the Oscar winner joked about sleeping with Jimmy's then-girlfriend Sarah Silverman.

Remember that 2009 "I'm f---ing Matt Damon" sketch?

Well, that relationship may have ended soon after, but the gag has persisted to this day.
