Ben Affleck brought his daughters Seraphina and Violet Affleck along to the farmers market in LA yesterday. He enjoyed a fun weekend with his family, including Jennifer Garner and their son, Samuel Affleck. Ben and Jen spent time with their kids on Saturday, too, and visited a friend's house as a fivesome. Ben's back in LA after a stint in Puerto Rico, where he shot Runner, Runner with costars Justin Timberlake and Anthony Mackie. His next movie to hit theaters is Argo, which is due out Oct. 12. Before that date, Ben will take the picture for a debut at the Toronto International Film Festival in September.
