Madonna has apologised for her use of the words 'rape' and 'terrorism' in relation to her album being leaked recently.

Last week, she took to Instagram to vent her fury at the leak, saying "This is artistic rape!! These are early leaked demo's [sic] half of which wont even make it on my album the other half have changed and evolved. This is a form of terrorism. Wtf!!!! Why do people want to destroy artistic process??? Why steal? Why not give me the opportunity to finish and give you my very best?""

In a recent interview with The Guardian, she said "I’m sorry if words alarm people, but that’s what it felt like. It was not a consensual agreement. I did not say ‘hey, here’s my music, and it’s finished.’ It was theft."

At the weekend, she made six songs from 'Rebel Heart' available to those who pre-ordered the album, which is due for release in March.
