The 48-year-old Justice League star's ex-wife Jennifer Garner was caught putting her baby daddy to work around the house over the weekend.
Affleck was photographed unloading a glass reptile tank from Garner's trunk and into her Los Angeles home through the garage.
Affleck kept it casual, and sadly, his shirt remained on for the manual labor forced upon him by his former wife on Father's Day.
Wearing black jeans and a matching t-shirt, the Academy Award winner didn't even break a sweat. Thanks to that one workout with J Lo, Affleck lifted the heavy box with ease.
As for Garner, she rocked a pair of loose-fitting overalls and a white shirt for her quick reunion with her ex.
Affleck and Garner have remained close since finalizing their divorce in 2018. They are committed to co-parenting their three children -- Violet, 15, Seraphina, 12, and Samuel, 9.
The exes aren't just friendly with each other. Garner is still tight with Affleck's mom, Christine Boldt.
Garner was seen greeting her former mother-in-law with a hug and kiss when she dropped Samuel off at the actor's nearby home.
"Jen gave Chris Affleck a hug and a kiss," an insider E! News of her Sunday drop-off. "They all seemed very cordial and happy to see each other. It looked like Ben had a nice low-key Father's Day at home with his family."
Despite their close friendship, Garner wants nothing to do with Affleck's reunion with J Lo.
The 13 Going On 30 actress "doesn't want to be a part of the circus or media attention in any way," another source told E!
"She's trying to live her life and raise her kids and the last thing she wants to be doing is be dealing with Ben's love life," the insider revealed, adding, "Her focus is always on the kids' happiness and Ben being a good father."
Ben and J Lo -- dubbed Bennifer -- have been inseparable since the singer ended her engagement with Alex Rodriguez in April.
The couple has traveled to Montana and has made numerous trips from L.A. to Miami to visit each other.
There's even talk J Lo is moving in with Affleck after she was spotted looking at a school for her children near his ritzy neighborhood.
