Jennifer Garner Santa Monica son Samuel Affleck

Jennifer Garner got some one-on-one time with the other man in her life as she and her sweet son Samuel made their rounds around Santa Monica on Friday. He's so cute!

The 40-year-old actress/supermom has been tending to her kids while still basking in the glow of her husband Ben Affleck's huge Oscar win last weekend and it's starting to show as she's looking noticeably slimmer. Probably from chasing her adorable brood all over town!
