That was a GOOD ****ing performance. She delivered. I can't believe it. She looked amazing, yes she lipped but who gives a ****, the choreo was fantastic and she did it well, the effects were great, she had amazing chemistry with G-Eazy. YES YES YES I am so happy.
It's called a medley. Started with her song, ended with her song. You stay (and FAIL) at trying for this to be another "Britney only introduced someone at the VMAs omgg".
