Beyoncé surprised her fans on Saturday by releasing a brand-new song.

The track, “Die With You,” debuted on a video that shows a casual Beyoncé, clad in a baseball cap and a T-shirt, singing to an apparently empty room as she plays accompaniment on a piano.

At the end of the song, as Beyoncé rises from the piano with a final chord, the camera turns and reveals that her husband Jay Z was the one filming.

The song was released on Beyoncé and Jay Z’s wedding anniversary, People reports. It is available on Tidal, Jay Z’s new music streaming service.
