Ben Affleck knows he lucked out in the best friend department! Perezcious readers know life has not been easy for Ben over the years. He underwent not one but two very public divorces, as well as struggled with alcohol addiction. Back in 2017, the filmmaker announced he completed treatment for a second time - around the time he and Jennifer Garner finalized their divorce. During the ups and downs and changes in his life, the one person who stayed by his side through it all? Even through Bennifer 2.0 (and possibly 3.0 if it happens)? It is his longtime bestie, Matt Damon.
