So far, everything is speculated based on that quote. All of us don't even know what really happened BTS between Katy, Taylor and those dancers. Maybe she wasn't just referring to the dancers, who knows maybe Katy tried to hire some of her crews from under her
People are really dense to think that Taylor would write Bad Blood because of that controversy alone Katy has been very mean to her for years and probably towards other artists too. It's not wrong for Taylor to write that diss track that is allegedly about Katy.
Whats funny... the articles on both Jezebel and Gawker majority of people commenting are totally won over by Taylor by this R.S. interview.
and even tho the tone of the Gawker article seems negative I think its supposed to be dark humor, because the author in the comments says she loves taylor and needs help
I still prefer the 2012 RS cover, just because she looks so messy, and the theme was a little more unique. But, ugh, I love this one so much as well. and she is wearing jeans and a white WET tshirt!!! AHHHHHH!!!!!
