"This ain't me. It's a friend of mine," Minaj jokingly wrote as the caption for one of the clips.
In the vids, the gal can be seen moving her impressive backside along with what sounds like it might be a sampling of some of her new music.
However, while Minaj plans to release a new tune in the next few days, the 31-year-old artist did take to Twitter to tell fans that the track they are hearing in the Instagram clips is something completely different.
"Lol. That's not THEE song. I promise," she wrote.
Meanwhile, when not shaking what the good Lord's given her, Minaj is keeping busy promoting her new movie The Other Woman, in which she costars opposite Cameron Diaz, Leslie Mann and Kate Upton.
The flick hits theaters on Friday.
