Diplo has put his stamp on tracks for M.I.A. and Santigold, but he’s setting his sights on even bigger pop stars. The Philly-based musician revealed that he’s been in the studio with U.K. producer Switch and Sleigh Bells’ Derek E. Miller for Beyoncé’s fourth album.

In a blog post, Diplo wrote that after playing indie duo Sleigh Bells’ raucous LP Treats for B’s team, they ended up going into the studio with the powerhouse performer. “Me and switch was in studio in nyc tryin to make tracks with derek and beyonce last week after we played her team their album,” he wrote. “Dunno if we gonna manage to finish but was good times.”

The “Paper Planes” producer recently lent his hitmaking skills to Chris Brown, co-producing the R&B singer’s Lil Wayne-assisted single “Look at Me Now” for his upcoming album F.A.M.E.

Several high-profile names have been attached to Beyoncé’s eagerly-awaited project, including Ne-Yo, Jim Jonsin, and Sean Garrett. It is expected to be released later this year.
