The pop star-turned-film director picked up the gong for 'Masterpiece' which features in her new movie 'W.E.' and Madonna admitted she was shocked to win but insisted it was not a solo effort.
She said: "This is a surprise. Thank you so much to the Hollywood Foreign Press for this acknowledgement. I need to thank my co-writers, Jimmy Harry and Julie Frost, my co-producer William Orbit, who's not here, whom I adore.
"I would also like to thank my manager, Guy Oseary, who I spend most of my time beating up on. But seriously, he harangued me for the entire time I was filming and editing my movie to write a song. And I said, 'Please, Guy, I'm trying to focus on being a director and I want people to pay attention to the film and I don't have time.' So then I finished the film and I started making my record and somehow magically and miraculously the song emerged, 'Masterpiece,' so thank you, Guy Oseary, for being so irritating."
Madonna's win came after fellow nominee Sir Elton John, who was up for the same prize for his song 'Gnomeo and Juliet' from the movie of the same name claimed she had no chance of winning.
He said: "Mary J [Blige] might win for 'The Help' - Madonna hasn't got a f***ing chance."
When interviewer Carson Daly joked, "Those are fighting words," Elton snapped, "They're accurate words!"
