Watch: Here's Katy Perry's brand new song 'Chained to the Rhythm', feat. Bob Marley's grandson

Katy Perry teased the opening bars of her brand new song 'Chained to the Rhythm' on social media the other day, and everyone agreed that it has a distinctly reggae vibe.

That was probably down to the fact that it features Bob Marley's 20-year-old grandson, Skip, who was recently signed to Island Records - the label that his grandfather had such huge success on.

Perry's latest track - which she made available for fans to listen to in various cities around the world the other day, by placing a mirrorball with a headphone jack at well-known locations - was also co-written by Sia.

The track has a vaguely political edge, with lines like "So comfortable, we're living in a bubble / So comfortable, we cannot see the trouble / So put your rose-coloured glasses on, and party on".
