While Jennifer Lopez is keeping fans guessing about her relationship status with Kevin Costner, J. Lo's ex, Ben Affleck, is making some post-divorce dating moves of his own. Though there doesn't appear to be a specific person who's captured Affleck's heart,

Ben Affleck is "casually dating" and "very focused on work" following his and Jennifer Lopez's divorce, a source exclusively tells PEOPLE.

According to a source who dished to People, Ben's "casually dating" but romance doesn't "seem to be a focus." Hence the "casual." Apparently, the actor is "very focused on work" at the moment, and "if he's not filming, he spends long days at his office," not to mention with his three kids and Jennifer Garner.
