While performing in Pittsburgh on Wednesday, Ariana Grande got choked up over her late ex-boyfriend Mac Miller.
The scene left some fans concerned.
But we don't think there's any reason to be worried.
Mac and Ari remained close until the time of his death last year.
He's only been gone for nine months.
It makes sense that his passing is still a deeply personal subject for Grande.
