Music producer Nile Rodgers was determined to quit drugs 17 years ago after making a fool of himself at Madonna's birthday party.
The Chic star teamed up with Madonna to produce her Like A Virgin album in 1984 and the two became pals, but he tested the friendship when his severe drug and alcohol addictions got the better of him at the singer's bash.
He tells UsMagazine.com, "She had a birthday party at her house in Miami Beach (Florida). I was on a three-day binge and up all the time partying... I didn't even want to go to sleep. I ran into Madonna at a club called Liquid and she invited me over for her birthday party.
"My behaviour, which I don't remember at all, was not so cool. I am almost positive that I was the last person to leave. And I was carried home and it was really ugly. I was so embarrassed I didn't even talk to Madonna for a long time.
"And then when I saw her and I apologised, she looked at me and she said, 'Oh no, you were just a little drunk.' I was like, 'Here I was ready to have a big apology. A little drunk? Do you know I was so embarrassed I haven't had another drink or drug in my life? It was hardly a little drunk.'
"But to her it was nothing. She's probably seen a lot worse. But thank god it all turned out just fine and when I look back upon it, it was completely embarrassing, way out of character for me and it was a resetting of my artistic and moral compass. Honestly, I haven't touched drink or drug again - and that was, like, 17 years ago."
