Madonna seems to have 'teased' a new song called 'Messiah' via the medium of — YOU KNOW IT — Instagram.
Firstly she popped this picture online with the caption, "Coming soon.….…#promise #keep#sorceress#deep".
'#deep'.
Then she backed that up with a short video of some people playing some dramatic-sounding strings and included a 'messiah' hashtag.
So there we have it.
