Madonna's manager Guy Oseary has revealed that she's really "upset" with today's demo leak and that she's disappointed with those responsible. 

Earlier this morning, November 9, a track entitled 'Give Me All Your Love' found its way online and was soon confirmed to be a demo from the Queen of Pop's forthcoming new album.

Oseary took to his official Twitter page to talk about the situation and explained that although the positive reaction is great, it's unfair to release unfinished music:

"I'm very happy with the positive reaction to the demo, but we are very upset with whoever leaked the song!!!!!!!! Madonna told me this morning "my true fans wouldn't do this"... whoever is responsible for this leak, we ask that you please stop!.."

Following an onslaught of questions from excited fans, Oseary went on to confirm that Madonna's long-awaited new record features a "beautiful ballad she wrote for the movie" she recently directed and at this moment in time still doesn't have a title.
