Has she? Taylor kinda did a shady diss at Adele during the Golden Globes, supposedly she left shortly after Adele won for Skyfall.
Oh! Come on, stop the shading here. She may have left for other reasons! Anything the woman does, there has to be some ulterior motive. But why? You know what I call that jealousy! It is true! I am certain that others may have left too! But Why is no one complaining about them! Don't be assuming what may not be reality.
Well she's one of my faves so she hasn't dissed herself. Katy plenty. Miley? I guess and Justin? Probably. She hasn't come right out at least not that I know of and dissed Miley and Justin. She hasn't dissed my other faves though
