Could also be when he got the vanguard award that she presented and he spouted off saying that it was MTV's idea?
Even though he called and asked her to present
Holy shit. I've just watched the speech I was talking about there...
It's 360 degree footage so you can actually find Taylor and watch her throughout (she goes to stand over to the left with Kim). The man is a fucking bellend. Narcissistic dickhead. Ugh. He stands there in silence for over 2 mins just to get applause btw. Poor Tay is literally dumbfounded by the end.
I remember her talking about this during the lover era!!! https://www.rollingstone.com/music/music-features/taylor-swift-rolling-stone-interview-880794/
“But he called me up, maybe a week or so before the event, and we had maybe over an hourlong conversation, and he’s like, “I really, really would like for you to present this Vanguard Award to me, this would mean so much to me,” and went into all the reasons why it means so much, because he can be so sweet. He can be the sweetest. And I was so stoked that he asked me that. And so I wrote this speech up, and then we get to the VMAs and I make this speech and he screams, “MTV got Taylor Swift up here to present me this award for ratings!” [His exact words: “You know how many times they announced Taylor was going to give me the award ’cause it got them more ratings?”] And I’m standing in the audience with my arm around his wife, and this chill ran through my body. I realized he is so two-faced”
