I feel like she is mainly coming from the Nicki/Miley thing & Kanye maybe.
I am only sad for Miley, because she was actually a cute host and for Taylor, she was NOT looking good performing with Nicki and lipsync-ing on top of that... She should've pulled 2010 Gaga and just get her awards.
Eveyrone including myself goes in on Pink for being, bitter/pretentious or w/e. But I see where she's coming from. Whether or not it needed to be said? Idk.
