An Instagram photo is fueling rumors that Nicki Minaj could be featured on Madonna's next album. 

Both Madonna and Nicki posted a photo together on Monday.  Madonna's caption seems to indicate that they may have been spending time in the studio.  It reads: "We go Hard or we go Home, we Gon Do this all night long! #werk." 

The superstar has made a habit of posting photos with collaborators like Diplo and Avicii since starting work on the album earlier this year. 

Nicki's caption, however, suggests that the meet-up happened by chance.  She writes, "My trip to New York isn't the same unless I bump into the Queen." 

Fans remain in the dark as to the release of Madonna's highly anticipated follow-up to MDNA.
