Madonna is said to be fuming after a demo of a new song leaked online.
The pop star's manager asked whoever was responsible to stop leaking tunes after the song Give Me All Your Love hit YouTube months before its expected release.
But Guy Oseary admitted they were happy with the positive reception the cheerily upbeat and dubstep-infused track had received.
He said: "Madonna told me this morning 'my true fans wouldn't do this'... whoever is responsible for this leak, we ask that you please stop!".
"Im very happy with the positive reaction to the demo, but we are very upset with whoever leaked the song!!!!!!!!"
