Well, that was fast.

Taylor Swift , 23, has reportedly broken up with her latest suitor, Harry Styles, 18.

Sources confirmed to Page Six that the pop star's romance with the One Direction member has come to an end following a "blow-up" fight the couple had while on vacation in Virgin Gorda in the British Virgin Islands. Swift was seen looking particularly sad as she took the boat back to the airport on Jan. 4 all by her lonesome.

While Swift packed her bags, Styles stuck around and was spotted living it up in a hot tub full of people -- including billionaire Richard Branson.

The split isn't too surprising, according to People magazine's source , who revealed that although the couple appeared to fall for each other quickly, no one took their romance seriously.

Reps for both stars have yet to comment on the reported breakup, but Swift's recent tweet speaks volumes.

The day after the couple reportedly broke things off, Swift tweeted a lyric from her hit song "I Knew You Were Trouble," which was rumored to have been written about Styles before the two reunited this past November.

The couple reportedly met last year at the Nickelodeon Teen Choice Awards, where they were introduced by their mutual pal Justin Bieber. After a brief but failed romance the couple were reunited during an "X Factor" taping this fall and were spotted together in Central Park in what looked like a highly orchestrated photo op. The couple continued to be seemingly inseparable after their NYC trip, and most recently they weren't shy about puckering up in public on New Year's Eve in Times Square.

If the "Haylor" relationship has indeed come to an end, it's par for the course for Swift, given that many of her relationships seem to go south around the three-month mark.

And as many have already joked, all we can do now is wait for Swift's inevitable song about the breakup, which will aptly be titled "Wrong Direction."
