Taylor Swift Posts Bikini Pic With Beau Calvin Harris

— -- "Swan goals."

And with that short caption, Taylor Swift posted and acknowledged her relationship with DJ Calvin Harris for the first time.

The two have been photographed holding hands at dinners and awards shows, but have yet to speak publicly about the rumors they are dating.

Swift, 25, Wednesday posted a poolside pic with the DJ, 31, that shows the two are having fun hanging out together.

The two first showed up in public together in February at the Brit Awards in London. Then, they stepped out in public, once in New York for dinner in May.

They enjoyed dinner at L'asso in Manhattan and were photographed holding hands en route back to her apartment.

"They seem pretty happy together," a source told ABC News.
