Ben Affleck and ex-wife Jennifer Garner were seen co-parenting smoothly as they met up and left together in a car in Santa Monica. The former couple, who share three children, appeared to be on good terms and were dressed casually for the meeting. Affleck is currently celebrating his one-year wedding anniversary with Jennifer Lopez, but he and Garner have maintained a healthy and functioning relationship for the sake of their children. Affleck is also busy producing several films, including one starring Lopez.
