The 22-year-old Vogue model walked barefoot on a concrete path, sporting a black and white polka dot string bikini with a matching robe.
She was followed behind by her husband Justin, who went barefoot and shirtless in a similar polka dot pajama bottoms.
At one point, a shirtless Justin was seen giving Hailey a piggyback ride while styling on the grass.
For one set up, Hailey changed into a pretty pink lace dress with ballet flats, while Justin wore a floral print shirt and black shorts.
The married couple had a lot of fun during the outdoor shoot.
