Swift was caught on camera kissing and holding hands with actor Hiddleston during a romantic outing on the beach near her mansion in Watch Hill, Rhode Island.
The 26-year-old "Bad Blood" singer wore a brown sweater and blue skirt while Hiddleston, 35, donned a jacket, blue button-down and dark jeans.
At one point in a sweet gesture, he took off his jacket and put it around her shoulder to keep her warm.
The couple looked smitten in pictures. They took a stroll together and sat on one of the big rocks scattered on the beach while enjoying the beautiful scenery. They also took selfies.
