Madonna wept with rage after an angry studio bust-up with producer Pharrell Williams.
The pair clashed while collaborating on Madonna's new album 'Hard Candy' - and the Material Girl was shocked Williams was brave enough to stand up to her.
She reveals: "Pharrell made me cry. You know when you get angry with someone and you're spitting snot.
"I was in a sensitive mood in the studio and I didn't understand the rhythm he wanted me to sing in, and he was giving me a hard time.
"I was taken back by how he was talking to me."
Rather than walk away, the pair decided to clear the air, and patch things up - and they are now firm friends.
She adds: "We went upstairs and I said, 'You can't talk to me like that,' and burst into tears. And he said, 'Oh my God, Madonna has a heart.'
"We had it out and now I love him and we make great music together."
