Anne Hathaway , in a Piamita x Jo de Mer  bikini, and Adam Shulman grinned as they strolled a beach in Oahu, HI, on Wednesday, but their sandy afternoon wasn't all smiles. While swimming in the water, Anne cut her foot and had to head to dry land, where Adam bandaged her injury. They quickly got back on track with their fun outing, though, walking near the ocean, showing PDA, and even stopping to take pictures with fans. Anne and Adam have been relaxing in the Hawaiian sunshine since Sunday and spent Tuesday exploring the island. The duo went for a hike, picked up lunch from a taco truck, and Anne even went for a jog in her bikini .
