It was an on-stage blunder that saw her smacked in the face by a wing being worn by Victoria's Secret angel Elsa Hosk.
Grande joked about the incident on her Twitter account after her show.
If you look at photos from the fashion show, you can almost pinpoint the moment that Grande took a wing to the face.
Here she is, and all's good. Elsa moving in for the kill.
She's singing her heart out ...
WHAM! What was that?
Watch where you put those things, girl!
But in the end, all was fine.
