Vocal sensation Ariana Grande has opened up about the naughty meaning behind her song "Side To Side".

She performed the song at the MTV VMAs last weekend with collaborator Nicki Minaj and told the music TV channel afterwards that it is about having a very active sex life: "That whole song is about riding leading to soreness. 'Ride d**k bicycle' is the lyric, indeed."

On August 30, writer and actress Lena Dunham expressed her surprise about the song's subject matter: "Jack just explained that the song Side to Side is about getting railed so hard you can't walk. SO MANY EMOTIONZ."
