Ariana Grande has arrived. She's in the news every week and now she's becoming quite the comedian (Pete Davidson's rubbing off on her). In a new sketch with Jimmy Fallon and the Tonight Show, Ariana Grande's ponytail is the star of the show as it has a mind of it's own. From helping Jimmy get a drink to signing albums on Ariana's behalf AND fighting crime, the ponytail is pretty much it's own person. I still can't get over the grunt it makes when moving around. Check out this hilarious new clip of Ariana Grande's special gift in the video below!
