Ben Affleck and Jennifer Garner Get Together For Their Kids' First Day of School

Ben Affleck and Jennifer Garner met up in for their kids' first day of school in LA on Tuesday. The former couple was spotted on the street together after dropping off their little ones; Jennifer was clad in workout clothes, clutching notebooks and chatting on her cell phone while Ben looked into the distance. The two have been keeping a united front for the sake of their three children, Violet, Seraphina, and Samuel, though they appeared to have spent the Labor Day weekend apart. Ben took on daddy duty in LA while Jen attended the Telluride Film Festival, where she screened her new film Wakefield with Bryan Cranston on Sunday. They did, however, celebrate Ben's 44th birthday as a family at a Montana resort last month — sources told People that they "spent the week together and enjoyed outdoor activities like hiking, biking, and swimming," adding, "Ben is happiest when he's spending time with his family."
