Madonna back to the Studio! Mirwais involved?

Just few moments ago Madonna has posted on Instagram with a brief video that she has entered the studio again!

While she has assured that the music she was singing along on the Instagram video was ‘NOT new music’, she also hashtagged Mirwais, her longtime collaborator who has worked on records such as ‘Music’, ‘Confessions On A Dance Floor’ and ‘American Life’.

Is Mirwais involved in this new project? Has Madonna secretly been planning to work with Mirwais all of this time? What’s sure is that the hashtag #mirwais is no coincidence, we shall see!
