Jennifer Garner appeared to be in a great mood while walking with her son Samuel in Santa Monica, California on Thursday morning.

The 52-year-old performer flashed a smile as she held the hand of her youngest child, 12, while they crossed a street.

The actress - who recently hosted a virtual reunion with her 13 Going On 30 costars - wore a bright green half-zip sweater bearing a logo for her children's food company, Once Upon A Farm.

Garner also wore a pair of black leggings, which clung tightly to her toned legs, as well as a pair of multicolored running shoes.

The Primetime Emmy Award-nominated actress' gorgeous brunette locks were tied into a loose ponytail as she held on to her son's lunch bag.

The Alias star shares Samuel with her former husband, Ben Affleck, whom she initially met while working on the set of the 2001 feature Pearl Harbor.

The pair went on to tie the knot in 2005, and they welcomed Samuel into their family in February of 2012.

Garner and Affleck went on to separate three years later, and their divorce was finalized in 2018.

The Daredevil actress is currently developing the upcoming holiday-comedy feature Mrs Claus.

The performer was first linked to the project earlier this month, when Deadline revealed that she had signed on to star in the film.

Although no director was attached at the time, it was announced that Leah McKendrick would be writing the movie's screenplay.

Specifics about the upcoming feature's plot points are currently being kept under wraps.

In addition to leading the feature's cast, Garner serves as one of the project's producers, alongside Reese Witherspoon.

The actresses recently worked together on the thriller television series The Last Thing He Told Me.

Witherspoon solely worked as one of the project's executive producers, and Garner served as both a producer and the project's star.

The show premiered on Apple TV+ last April and was met with a mixed to negative critical reception.

It was announced that The Last Thing He Told Me had been renewed for a second season this past March.
