Garner, 52, was photographed walking alongside the 15-year-old, who wore a pair of pajama pants with a white and green patterned T-shirt, as they left the grocery store together with their bags marked Vicente Foods in Brentwood, Calif. on Saturday.
The “13 Going on 30” actress, who also shares daughter Violet, 18, and son Samuel, 12, with ex-husband Ben Affleck, looked active as she wore a pair of navy blue leggings and a loose-fitting navy top which she rocked with some sneakers.
Ben and Garner’s middle child wore a similar edgy look to a different outing in April which included an oversized graphic T-shirt paired with cargo shorts, sneakers and mismatched socks.
The grungy look was completed with silver chained necklaces and bracelets. Seraphina was meeting Garner for a nail appointment at the time.
Earlier this month, Seraphina met up with dad Ben — who notably wore his wedding ring amid continued rumors of marital woes with Jennifer Lopez — for lunch in Los Angeles.
The “Gone Girl” actor, 51, has been seen with and without his ring on several outings since J.Lo divorce speculation began swirling in May.
The rumors were fueled later when the couple spent their second wedding anniversary on opposite coasts.
Most recently, a source claimed to OK! Magazine that the actor found his estranged wife to be “his dream woman” but she wound up delivering “drama all the time.”
“He’s feeling down about it and is upset and depressed it didn’t work out, even though he knows ending it is the right thing to do,” the source said.
The insider also said that the couple’s different lifestyles further contributed to their breakup.
“Jennifer has a big entourage that follows her around daily — glam squad, videographers, photographers, assistants, trainers,” the source told the outlet.
