In addition to having Kanye West work on her upcoming album Rebel Heart, Madonna says she returned the favor and contributed to a song on the rapper's own forthcoming LP, So Help Me God.

The pop queen told Complex in a new interview that West's schedule prevented him from offering feedback on her full album, but he ended up "working on four songs, and then we wrote another song together, which is going to be on his record."

She also confirmed that Drake's new song "Madonna" (and her love for the song) isn't the extent of their musical relationship: "We're gonna work together," she said. "Yeah, baby, it's in the pipeline."

Rebel Heart releases Tuesday, while West has warned that So Help Me God could arrive at any moment.
