Jennifer Garner & Ben Affleck Take the Kids to School Together

Jennifer Garner and Ben Affleck ride in the front seats together while running errands on Tuesday morning (September 8) in Brentwood, Calif.

The estranged couple spent the day together after dropping their three kids – Violet, 9, Seraphina, 6, and Samuel, 3 – at their first day of school for the new year.

“They smiled and chatted during the morning run,” a source told People about the outing. “There was no obvious tension between them.”

Jennifer was seen smiling wide later in the day while picking the girls up from their school.
