Taylor Swift and Calvin Harris post loved-up vacation pictures

Taylor Swift and Calvin Harris have marked their year-long romance by sharing sexy photos from their tropical vacation on social media.

The Shake It Off singer and Scottish DJ recently celebrated their one year anniversary and it seems they decided to honor the milestone by heading off to an undisclosed beach location.

Both stars took to their respective Instagram accounts on Tuesday (15Mar16) to share intimate images from their holiday, including a photo featuring bikini-clad Taylor posing for her beau, who showed off his toned body in a pair of red swim trunks in other pictures.

The pop star also posted a short video of her jumping on a large, inflatable trampoline floating in the water, and she can be heard asking Calvin, "Watch, watch - are you watching?", before taking a not-so-graceful dive into the water, much to her boyfriend's amusement. "It hurt a lot!" Taylor says in the video.

She also added in the caption, "That time when we finally took a vacation."

In another shot posted by Taylor, the initials "TS + AW" are written in the sand, with the latter representing Calvin's real name, Adam Wiles.

Earlier this month (Mar16), the happy couple also declared their love by sharing photos from the anniversary celebrations.

Taylor took to Instagram.com 6 March (16) to share a photo of a gold locket with "3.6 2015" engraved on the front, marking the date of their anniversary.

Writing in the caption to the photo, she gushed, "3.6.15 One year down!"

Meanwhile, Calvin shared a video on Snapchat, featuring a cake decorated with hearts and the phrase "1 Year" atop the chocolate frosting. In the clip, he says, "One year! We got one year cake! One year," before handing the spotlight over to his girlfriend, who also shared her excitement over their milestone.

The two were initially introduced to each other by mutual friend Ellie Goulding the night of the Elle Style Awards in London last February (15).
