It looks like Ben Affleck is starting to forego wearing his wedding ring.

The Batman v Superman: Dawn of Justice star – who, up until recently, had still been wearing his ring in the weeks after he and his ex Jennifer Garner announced that they were divorcing -- ditched the ring while out and about in Los Angeles on Tuesday.

An eyewitness tells ET that the 45-year-old actor also left his ring at home when he went on a family outing to Underwood Family Farms in Moorpark, California on Monday.

Ben was accompanied by his three children -- Violet, 9, Seraphina, 6, and Samuel, 3 -- as well as a nanny for the children.

The kids have been staying in the family home with their dad recently while Jennifer remains in Atlanta to film her movie. She will reportedly stay in town until Friday.

A source tells ET that the Oscar winner still sported his wedding band over the weekend while he and the kids went around the city, shopping at craft stores and enjoying Starbucks.
