Iheartradio removed the mid-September date from their article so If she was going to drop it on September​ 1st one could speculate she will perform it at the VMA's. I think the VMA's would be stupid if the weren't getting Gaga to perform because their viewership dropped a lot last year from the previous years.

She will perform on another big gala

They may be keeping it in a secret... Who knows...

She'll slay next year... I kinda understand her, applause performance was directed by VMA, not by Gaga... They sucks...

It's just impossible !!
