She's lip syncing this performance. The mic wasn't even by her mouth.
You should be smart enough to distinguish the voice in the studio/live. I'm a fan and I know what I'm saying, you may have heard the base. She performed live.
She also messed the lyrics up.
I'm glad someone thinks this is lip syncing, which means she's improving her vocals. I'm feeling this too (except the iHeartRadio mess).
