They're not even officially together, despite the many sightings, and already fans are bemoaning the "inevitable" break up.
1D mega-fan Ash Collette went one step further by making a YouTube video called 'The Haylor Song' (taken from blending Harry and Taylor), a parody of Taylor's hit 'I Knew You Were Trouble'.
In it, the singer expresses her savage disappointment as a One Direction fan, now that her crush is off the table.
"And the saddest fear, comes creeping in/That we'd be pissed off, if he loved anyone, or anything. Yeah, yeah, yeah," she sings.
Equal parts impressive and mildly disturbing, we think. Bleeding hearts of the global 1D-fanclub unite!
