They're practically matching!
While the actress usually keeps her two-year-old off social media — it's nearly been a year since the last time she shared one — we can see why she couldn't help but share this sweet shot!
Reese even captioned it:
"Sweet lil walks with this sweet lil guy ❤️ #Vacationmood @draperjamesgirl."
He looks so happy by his mom's side!
Hope these two enjoy their little vacay — and may there be more matching outfits in their future!
