Ben Affleck grabbed ice cream with Jennifer Garner and Seraphina in LA yesterday. He hung out with his wife and youngest daughter ahead of his big premiere for To the Wonder later that night. We may see more instances of Ben hanging out with his kids without Jennifer, as he recently revealed that he is going to be taking on a "Mr. Mom" role with Violet, Seraphina, and Samuel as his wife prepares for several new projects. She will reportedly costar with Kevin Costner in Draft Day, an upcoming football drama, and has press duties for Dallas Buyers Club to look forward to later this year.
