According to several sources, Taylor Swift and Harry Styles broke  up sometime last week, which puts their relationship somewhere around the  two-month mark.

Here's what happened:  They flew to the Virgin Islands TOGETHER on  January 1st . . . had a "heated argument" . . . and then broke up.  Just  like that.  Someone even took a photo of Taylor sitting alone on a  boat.

So, Taylor decided to come back to the states while Harry accepted a sweet  invitation to party on British billionaire RICHARD BRANSON'S  private island.

Neither of them said a word about it . . . and then on Saturday Taylor opened  the door when she Tweeted, "Til you put me down".  That's a line from her  song "I Knew You Were Trouble", which is supposedly  about Harry.

The full line is "Flew me to places I'd never been / so you put me  down".  The "put me down" part would be Harry breaking up with her.
