Ben Affleck and Jennifer Lopez are helping their kids give back ... working hand in hand with their daughters to help fight hunger in the community, and doing the grunt work.
It was a joint effort over the Thanksgiving weekend at Ben's home in Pacific Palisades, where they hosted a food drive for Rise Against Hunger.
As you can see, Ben and Jen were tasked with unloading a huge truck and hauling 50-pound sacks of rice and goods into the house ... and he flexed his muscles, even slinging 2 bags over his shoulders at a time.
J Lo was pretty impressive too, doing it all in high heels!!!
Ben's oldest daughter, Violet, appeared to be leading the effort ... and his other daughter, Seraphina, was doing her part too along with Jen's daughter, Emme.
Food insecurity and hunger is a huge issue nationwide ... and Rise helps provide food and support to local communities.
Ben and Jen haven't officially merged their broods yet -- they're not married or even engaged -- but they sure are acting like one big happy modern fam.
