The 44-year-old "Miracles from Heaven" star was pictured looking sad and keeping her head down while the actor talked to her in their car, reported Ace-Showbiz.
In a sleeveless white top paired with jeans and black shades while carrying a bible, Garner looked sad as she stood next to Affleck, who donned a grey T-shirt, jeans and a Red Sox cap.
Garner and Affleck announced their split last year after ten years of marriage, but none of them has filed for divorce. The two are still on friendly terms and frequently spend time together with their three kids.
