Ben Affleck and Jennifer Garner took the kids to the local YMCA Christmas Tree yard after church on Sunday. Despite being divorced and living apart, the former couple spent the entire Thanksgiving weekend together as a family. That said, the two didn't look so happy together after church yesterday, as they were doing the most exciting thing ever for their kids -- buying their Christmas tree!

They really made it a point to spend the entire Thanksgiving break together with the kids -- going up to Santa Barbara for a night with the entire family, church on Sunday with Ben's mom and the kids, and then straight off to buy a Christmas tree!
