As everyone in the free world now knows, Taylor Swift has learned to shake off the haters. All the way to number-one, in fact.
But there's one fellow artist Swift admits she can't just forget about, so much so that she penned the upcoming song "Bad Blood" about this unnamed individual.
"For years, I was never sure if we were friends or not. She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?'" Swift told Rolling Stone.
"[Then last year] she did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy!"
Whoa! A controversy surrounding Taylor Swift's personal life that does not involve a guy?!? Tell us more.
