Speculation surrounding Taylor and Harry - or 'Haylor' as some have taken to calling them - has been growing steadily over the past week, after reports of all sorts of necklace swapping, soundcheck watching and cheesburger flirting surfaced.
The X Factor USA host Mario Lopez added more fuel to the Haylor fire when he revealed on his radio show that he'd spotted the pair walking 'hand in hand.'
"Taylor Swift was the special guest performer, and [here's] a little inside scoop for you," he said. "During rehearsals, Harry from One Direction came and slapped me on the back, and said, 'Hey, Mario, how ya doing?' And I said, 'What are you doing here?' And he sort of [pointed] toward Taylor.
"So Taylor Swift and Harry from One Direction - you heard it here first. [They're] officially hanging out, I can say that much."
Now it seems that SOME vile 1D 'fans' have threatened Swifto over the budding romance, with one user writing: 'If u dating my harry, i kill u [sic]' and another tweeting: 'I'll murder Taylor Swift. She will not date my Harry.'
CHRIST there's some crazy-ass people in this world.
This isn't the first time that a girl linked to the curly-haired love bot has been targeted by twitter trolls either.
Earlier this year model Emma Ostilly was forced to delete her twitter account after receiving a barrage of abuse over photos seemingly showing her sharing a kiss with Hazman - while Made in Chelsea's Caggie Dunlop has revealed that she was also targeted after being snapped driving home with the star.
However people might feel about Harry's dating choices, it's NEVER OK to send sick death threats. Don't you agree?
