Like mother, like son! Such a cute image of Ben Affleck and his mom Christine after morning drop-off at daughter Seraphina and son Sam's school -- both clutching their coffee cups, enjoying the brisk morning air.

Grandma Christine is a near-constant presence in the kids' lives, making regular visits to the family -- both with Ben AND Jen.

Speaking of Jen, she's enjoying her social life these days, always making time for girlfriends, exercise and morning walks -- as she did Tuesday with a gal pal. Watch!
