Madonna has revealed that she is collaborating with DJ and producer Diplo.
The singer posted two photos of her time in the recording studio to her Instagram account.
"Working with @Diplo got me like................WHAAaaat?" she wrote on the first image.
The second image is captioned: "Diplo is a slave driver! Got me working all hours of the night in the studio. Had to sneak into the bathroom! #clicclacclicclacbitchgetoffmyback."
Madonna has also cited Natalia Kills, Toby Gad and Avicii as fellow collaborators in the studio.
Earlier this year, Madonna confirmed that she is working on her 13th studio album.
