This tweet seemed to be in reaction to Swift's comments
made to Rolling Stone
magazine about a fellow female singer that, though she didn't identify, she claimed had done her wrong. "For years, I was never sure if we were friends or not," Swift, 25, said. "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?'"
