The former couple took Violet, 11, Seraphina, 8, and Samuel, 5 (not pictured), to watch the patriotic parade on Tuesday (July 4) in Brentwood, Calif.
Ben was spotted chowing down on a hot dog and Diet Coke, and Jennifer was seen walking the family dog (who adorably wore a red and white scarf).
The group sat in the grass together, shading themselves from the sun underneath colorful umbrellas.
Jennifer sported a red and white tank top, blue jeans, and a straw hat, while Ben rocked a red(ish) t-shirt.
Late last month, the friendly exes, who filed for divorce in April, reportedly flew to Baker’s Bay in Great Guana Cay in the Bahamas for a vacation with their kids.
