Well, whaddaya know? Here's a nice photo of Ariana Grande warming up before a show. You can tell because it's full of classic Grande-isms...
Ponytail? Check.
Thigh high boots? Yep!
Plaid?! Dooooiiiii!
But, as the headline of this post you so graciously clicked on reveals, it's NOT a picture of Ariana Grande — it's actually Chrissy Teigen, aka Ariana Venti!
See?! It really was Chrissy all along! What a wild ride!
