Jennifer Garner and Ben Affleck brought their two daughters, Violet and Seraphina, along to visit the Children's Museum in NYC today. The girls have been busy exploring the Big Applewith their mother, Jen, and it looks like Ben's spending time in the city as well. Ben's getting into promotional mode for The Town, including a turn doing the interviewing with costar Blake Lively, while Jen's finishing up work on Arthur. He also just welcomed his 38th year last Sunday, and it looks like the whole Garner-Affleck clan is together to keep celebrating.
