Though the former couple split in June, they looked friendly with each other during the reunion. The two were seen just one day after the “Batman v Superman: Dawn of Justice” teaser trailer was released, which features Ben.
Last week, Affleck and Garner reportedly celebrated Thanksgiving together. A source told People, "They spent it as a family unit – all for the kids. They had a great time.”
Another insider revealed that Affleck took a break from shooting his new film “Live by Night” in Boston for the special family gathering. "[Affleck] looked very happy all weekend. He spent a lot of time at the family house.”
Ben and Jennifer are also apparently spending Christmas together. A third source said, "Jen and Ben are figuring out right now how they can best spend the holidays together. [Jennifer] wants to get along with Ben for the kids' sake."
