Matt Damon and Jimmy Kimmel's feud was on full display as they attended the World Series on Sunday. The longtime "frenemies" were spotted wearing "I'm With Stupid" shirts as they rooted for their favourite team — Matt wore a red shirt for the Boston Red Sox and Jimmy wore a blue shirt to support the Los Angeles Dodgers. While the two snapped a photo together before the game, they eventually used their mutual friend Ben Affleck as a buffer to sit between them, which awkwardly made both of their arrows point at the Justice League actor instead.
Of course, the whole thing was all in good fun. While Matt and Jimmy love to play up their "hatred" for each, the two are actually close friends in real life. Even so, we can't get enough of their "frenemy" moments whether it's Jimmy not letting Matt appear on his show, or Matt interrupting Jimmy during the Emmys. See their latest appearance ahead.
