The celebrity lovebirds recently celebrated one year together and soon after embarked on their first solo vacation as a couple.
"That time when we finally took a vacation," Swift captioned one Instagram video of herself jumping into the ocean from an aqua trampoline. In the clip, Harris -- born Adam Wiles -- yells across the water assuring his girlfriend he is watching her.
Harris also posted several sexy photos of Swift posing in two different bikinis. In one, a sunkissed Swift channels a swimsuit model near the shoreline; in another, she looks over to Harris' camera sporting messy waves.
Swift shared several more photos, including one in which the two are seen kissing just before the sunset, with the "Shake It Off" singer popping her leg. "TS + AW" is spotted in the sand of another, referencing the couple's initials.
Earlier this month, Harris gifted his girlfriend of one year a gold locket with the date they officially became a couple engraved on the front. "3.6.15 One year down!" Swift wrote in the photo's caption.
The couple reportedly started dating after meeting at the Brit Awards in 2015. They kept their relationship secret for several months before going public.
