Maybe Ariana Grande's 'Nonna' has never really heard a lot of Ariana's music or really listened to some of the lyrics because she was pretty shocked and even bored watching Ariana perform in Vegas.
Now, sure, the video is definitely edited to the parts where she's looking bored and shocked and we didn't really expect 'Nonna' to be singing along about the 'dick bicycle' in 'Side 2 Side' or anything even though that would have been INCREDIBLE!
