The two worked together on the song Mixdown on the upcoming disc. Madonna hasn’t released a CD since American Life.
The singer met the hip-hop singer on the set of Revolver with her husband, Guy Ritchie.
Andre said: "Madonna showed up on the set of Revolver and made me really nervous."
"She walked around the corner and I forgot all my lines."
"She asked me what I thought about music and where it was going and we talked about doing something on her new album."
Confessions of a Dancefloor will be in stores this fall.
