Madonna "Very Upset" Over Song Leak, Manager Says

"Give Me All Your Love," the first track off Madonna's new album, leaked online Wednesday. And she's not happy about it.

Madge's longtime manager, Guy Oseary, Tweeted after the leak:

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

Madge's album -- her first since splitting with longtime record label Warner Bros. -- should be finished within the next month.

In other potentially bad news for Madge, her critically panned film W.E. has been pushed back from a Dec. 9 release date to Feb. 3.
