Mike Tyson has explained how his collaboration with Madonna came about saying "Madonna calls you and tells you to come somewhere, you go."
The former boxer is listed as a collaborator on Madge's track Iconic, which features on her upcoming album Rebel Heart, and he told Rolling Stone, "I didn't know what the hell I was going there for.
"I'm just there having a good time and hanging out with Madonna. She has her producer there and I go into the studio and I didn't know if she wanted me to talk or rap.
"I just go in there and start talking. I'm talking about my life and things that I have endured. I'm saying some really crazy stuff. It was really intense."
