Not on at ALL.
Ariana brushed it off though, playfully asking "One of ya'll threw a lemon at me... SHITT!" before continuing on with the show like the boss that she is.
During the performance, she also surprised fans with a special appearance from Justin Bieber who went on to make a HUGE announcement which you can find out about here.
Ari closed out the set with hit single "thank u, next" before leaving the stage with a tearful thank you to the fans that still has us tearing up.

We love you Ari!
