We're pretty sure her big brother, Frankie Grande's, wide-eyed, invisible pearl-clutching, unintelligible, shriek-filled post-performance reaction Vine accurately sums up our feelings. (On a related note, it's clear that losing one's chill runs in the Grande family.)
And Frankie literally could NOT with his little sister's set.
It's safe to say that the "Big Brother" alum was freaking the Frankie out.
Frankie was living for the Glinda the Good Witch realness.
And we mean living.
We only pray he made it through her Best Song acceptance speech in one piece.
