Ben Affleck and Jennifer Garner were seen together in Santa Monica for a Halloween celebration at their children's school. However, they appeared tense during a conversation outside. Garner had a frown on her face, but later smiled as Affleck placed his hand on her bicep. They both dressed for fall weather during the outing. Affleck later seemed annoyed after backing his car into another vehicle. The couple finalized their divorce in 2018. This joint outing came after Affleck and Jennifer Lopez attended a birthday party together.
