Are Beyonce and Calvin Harris working together?

In a new piece of detective work, Your EDM has organized potential–though not definite–proof that a new song between the prolific producer and global superstar is in the works.

First, fans noticed that Beyonce used a clip of Harris and Frank Ocean’s recent collaboration, “Slide” in a post about time at the Oscars.

Harris reportedly commented with a heart emoji.

Last year, rumors surfaced that Harris was eager to collaborate with Beyonce after hearing her feature on Naughty Boy’s “Runnin’ (Lose It All).”

And earlier in the year, when discussing his new music, Harris claimed that he, “worked with the greatest artists of our generation.” Six days later, his collaboration with Ocean and Migos dropped.

And late last month, Harris hinted that more collaborations are in store.

We’ll just have to wait and see. In April, we wrote about five producers on Beyonce’s Lemonade you need to know.
