Kanye, yes. He deserves it for hooking up w/ the K-Klan and acting wack (I also didn't care for Yeezus, but that is another discussion).
Gaga gets enough hate by a certain obsessed group, so I'm not going to add to that. Kylie Minogue is so nice, I would never, and there is simply nothing to drag when it comes to Janelle Monae.
Why shouldn't I? I mean, we all get criticised at one point of our lives, and Xtina or Ariana will never dodge the bullet for me. If they mess up, I will drag them.
