The 23-year-old pop superstar performed the track with Nicki Minaj at the MTV Video Music Awards on Sunday (28.08.16) and the stage show featured Ariana and her dancers carry out a fitness-theme dance routine with them riding exercise bikes in super-sexy outfits.

Now Ariana - who is dating rapper Mac Miller - has revealed the lyrics are about how a woman might have to walk after spending too much time getting frisky between the sheets.

Speaking to MTV, she said: "That whole song is about riding leading to soreness. 'Ride d**k bicycle' is the lyric, indeed."

The line she is referring to is rapped by Nicki and states: "This the new style with the fresh type of flow / Wrist icicle, ride d**k bicycle / Come true yo, get you this type of blow / If you wanna Minaj, I got a tricycle."

While Ariana also sings: "I been here all night/I been here all day/And my, you got me walking side to side."

Ariana's racy confession shocked her famous fan Lena Dunham, who took to Twitter to reveal it was her musician boyfriend Jack Antonoff who had originally informed her what he thought the track was about.

She tweeted: "Jack just explained that the song Side to Side is about getting railed so hard you can't walk. SO MANY EMOTIONZ (sic)"

Ariana confirmed she is dating Mac on the red carpet of the VMAS - which were held at Madison Square Garden in New York City.

The relationship comes a year after she split from Big Sean following eight months of dating.
