Yesterday, it was confirmed that Katy Perry would be playing the Grammys this Sunday and probably using it as a platform to perform some new material.

Well, we now have an idea of just what the material might be as she's posted a teaser of her new song 'Chained to the Rhythm'.

By the sounds of the intro, at least, it seems to have a pretty Caribbean-flavoured vibe going on... would we go as far as to say 'reggae'? Yes, we would. Considering she's recently been espousing the virtues of Skip Marley - Bob Marley's grandson, whom she is said to be duetting with at the Grammys and whom she called 'The voice of our revolution' on Instagram - we can also assume that he features on it.

The full version is due on Friday, but hear the teaser below:
