Seraphina Affleck was too cute in her overalls yesterday while out in LA with her mom, Jennifer Garner. The whole Garner-Affleck clan, including dad Ben and Sera's siblings, Violet and Samuel, have been hanging out on the West Coast while they get back into their Fall school routine. However, Ben's got his third directorial feature, Argo, on the way, and it looks as though his promotional tour is under way before its Oct. 12 release. He popped up this morning in Spain at the San Sebastian Film Festival along with his costar Alan Arkin. Jennifer was able to accompany Ben to his last festival appearance — Jen and Ben celebrated Argo at TIFF along with their great friends Matt and Luciana Damon.
