Madonna has spoken out after two of her new songs found their way online.

Demo versions of 'Rebel Heart' and 'Wash All Over Me' recently were leaked on the web from her new album recording sessions.

Her manager Guy Oseary was the first to repond to the leaks, calling on fans to help catch the culprits.

Madonna has now taken to Instagram to admit she feels "violated" by the songs appearing online.

Posting a picture of a smashed iPod, the Queen of Pop said:

"This broken ipod is a symbol of my broken heart! That my music has been stolen and leaked! I have been violated as a human and an artist! #f*ckedupsh*t."

The singer has been busy for a number of months working on the follow-up to 2012's 'MDNA' with the likes of Diplo and Avicii.
