The 48-year-old Justice League star appeared to not have a care in the world while picking his 9-year-old son Samuel from swimming practice ahead of the weekend.
Keeping his pick-up look casual in a pair of black jeans, a hoodie, and a purple t-shirt, Affleck kept his mask on while brushing past photographers on Friday.
The star was seen bending down to greet his son -- who's long hair was soaking wet -- before safely guiding him to their awaiting SUV.
This is a complete 180 to less than one week ago when he picked Samuel up from practice.
While the trespasser has still not been caught, Affleck appeared unbothered while playing super dad after spending several days with J Lo.
After being photographed together in Montana earlier this month, the duo went their separate ways but remained in communication every day.
Their physical separation didn't last long.
"Jennifer was just in Los Angeles for a couple of days," a source told the outlet.
"It's a tricky situation since they live so far from each other, but they both seem committed to making things work," the insider added.
The Batman actor proceeded with caution as they walked past waiting shutterbugs ahead of the weekend, just days after a scary trespasser made his way onto the star's $20 million Los Angeles property.
That's because authorities are having trouble identifying him.
