I just got our neighbor who works in the ministry of justice and does this for a living to see it and he swore on his life that she said "It's Taylor Swift, that's right" and at the end of the video, after the Pepsi ad, she mouths "shake it off, shake it off"
If Taylor performs she'll get overexposed, she has been literally everywhere this era.
I don't think she needs this performance now, maybe for her next era.
