Jennifer Garner Shines in Leggings After Ben Affleck Reunion

looked very happy as she stepped out in over the weekend.

The 53-year-old actress flashed a big smile and later let out a hearty laugh while out and about in the city's Brentwood neighborhood.

She looked fit in a pair of skintight black leggings with thin white stripes going down the sides.

The mom-of-three, who shares her children with 53-year-old ex-husband , added a ribbed heather-gray sweater. 

She went makeup-free and rounded out the look with white-and-red socks and a pair of dark sneakers.

Her outing comes after earlier this month. 

The former husband and wife spent time with their youngest child, 14-year-old son Samuel, while running an errand.

They are also parents to Violet, 20, and Fin, 17.

Two months earlier, they'd also put on a united front while celebrating Samuel's birthday at a paintball park.
