Nicki Minaj is known for her raunchy Instagram posts and has even shared a couple of sexy dance videos in the past.

Sticking to tradition the "High School" rapper recently decided it was time to share a twerking video with her millions of followers.

The video focuses on the dancer's well endowed butt. Minaj posted two videos of the sexy moves but in the second clip she denied that it was her working her thing for the camera. She wrote the caption, "This ain't me. It's a friend of mine."

However, E! News hinted that the "Super Bass" rapper jokingly wrote the caption which begs the question if that was really her in the video?

In the short clip the female can be seen busting out some impressive moves during her booty dance along to the beat of what sounds like it might be a sampling of a new song.

With the unfamiliar music playing in the background Nicki Minaj quickly took to Twitter to address her curious fans. The 31-year-old told her Barbz, "Lol. That's not THEE song. I promise."

Aside from twerking on Instagram the hot artist has been busy promoting her new movie "The Other Woman" alongside stars Cameron Diaz, Leslie Mann and Kate Upton.

The movie hits theaters on Friday, April 25th.
