The 48-year-old Oscar winner and 47-year-old cinematographer were snapped wearing shorts and T-shirts (with similar straw hats) as they stopped for a quick smooch in the sand last Saturday.
Roberts and Moder met on the set of the actress's 2001 film, The Mexican, where he worked as a cameraman. They tied the knot the following year, and have three children together: 11-year-old twins Hazel and Finn, and 8-year-old Henry.
Last November, Roberts gushed to ET about how her husband inspired her performance in the 2015 film, Secret in Their Eyes, which they worked on together.
"We've done a number of things together, and it's always kind of nerve-wracking for me because he's my husband and I want him to think I'm awesome," said Roberts. "But this was a collaboration where I realized that if he hadn't been there I don't think I could have fashioned together the performance that I wanted to."
Speaking of couples we love, watch the video below for Roberts' take on how marriage has changed pal George Clooney.
