One such fan is Hailie Mathers, the 16-year-old daughter of rapper Eminem, who took to twiiter to vent her anger - telling Taylor Swift to 'stop wh*ring it about'.
Gulp. It seems Hailie has inherited her dad's knack for not holding back when it comes to saying what you think, then.
"if @taylorswift13 is really dating the love of my life @Harry_Styles i will not be happy.!" she wrote, following up with, "Dear @taylorswift13, please stop whoring around with every guy you see. We all know you're only doing it so you can make another album."
OUCH. Hailie wasn't quite finished there though, she sent a final message to Taylor, which read: "I, am never, ever, everrrrr, listening to your music againnnn @taylorswift13. LIKE EVER."
Ah, we see what you've done there, Hails.
It would appear that Hailie later regretted her Haylor-related outburst though - after receiving hundreds of responses to her comments she tweeted: "Wow. I didnt mean for people to react to my tweet in the way that they have it was just a bit of fun! Sorry @taylorswift13 for my immaturity."
Ah, well all's well that ends well, eh? It's Herreh's hair, Hailie - it's a bewitching thing...clouds judgement all over the place.
What do you make of all this Scapers?
