When will stage crashers ever learn? Concert security is actually pretty tight, and they’re quick on their feet, too.
Ariana Grande was performing her song “Moonlight,” when a random guy started walking up behind her (through the fog on stage too, very creepy). Once he finally got her attention after walking around her side towards the front of the stage, he waved at Ariana, then she waved back at him. At that same moment, he was grabbed and pulled down by security.
Just as he was being pulled off stage, Ariana stopped singing and calls out “hey, chill out!” Then she jumps right back into her performance, pulling off another one of her signature high-notes.
