Jen Garner Walking On Air With Son After Blissful Rendezvous With On-Again Boyfriend John Miller At Her Los Angeles Home

Garner appeared to be on cloud nine, holding Samuel's son while out and about on Wednesday.

The mom of three spent some quality time with her youngest child while running errands around the city, and she couldn't wipe the smile off her face.

Keeping her afternoon look casual, Garner was spotted trucking around L.A. wearing jeans, a plain t-shirt, and tennis shoes.

She seemed to be getting a jump start on Fall because nearby photographers caught the 13 Going On 30 actress slipping on an oversized turtleneck in an attempt to battle the chilly weather.

As for Samuel, he looked like the coolest little man.

Wearing forest green sweats, Garner and Affleck's son rocked a navy shirt with a love heart, sneakers, and his red face mask.

Showing he's not too old to show his mom affection, Samuel held onto Garner's hand tightly while exiting the building and into their parked car.

The CaliGroup CEO was photographed in her Southern California neighborhood and outside of the $14 million mansion she's currently renting, which happens to be minutes away from her famous baby daddy.

Miller emerged from his on-again girlfriend's home with what appeared to be bed head.

The duo was first linked in 2018.

Despite being together for two years, Garner and Miller's romance didn't get a chance to survive the pandemic. They reportedly ended their relationship in March 2020 "before LA went into lockdown."
