The 28-year-old Reputation artist still managed to show her patriotic side in a red, white, and blue stripped two-piece bikini while swimming and snorkeling with the 27-year-old actor.
The pair enjoyed the temperate climate and calm waters at a luxury resort in Turks and Caicos, where they made the most of their romantic vacation. They even got a little cozy in the surf as Swift rode on Alwyn's back through the idyllic blue waters.
While the lovebirds enjoyed the quiet, romantic holiday in relative privacy, fans of the pop icon were left wondering if this marked the end of Swift's Fourth of July party tradition.
For years now, the singer and her squad of besties -- which included super models, singers, actress and social media stars -- all gathered at Swift's Rhode Island estate for FOMO-inducing festivities that included barbecues, fireworks, patriotic inflatable bouncy houses and more.
