Firing back! Katy Perry makes several not-so-subtle references to her ongoing feud with Taylor Swift

In her new song Swish Swish she makes several references to the ugly feud she has with the 1989 hitmaker, making it clear she was not going to back down from their very public spat. 'Ur game is tired, you should retire,' she sings.
Things get even more intense in the Swish Swish music video - which features stars from Glee, Stranger Things, Game Of Thrones and Glow - as there are plenty of nods to the former country music star and their power struggle. Nicki Minaj even pops up (wearing what looks like a Bad Blood costume) to make it clear she is on Team Perry.

The video was released on Thursday, the day after Swift announced her November 10 album Reputation and just days before Perry is set to host the MTV VMAs on Sunday.
It is rumoured that Swish Swish is in response to Taylor's Bad Blood released in 2014 which was reported to be a Katy diss track.
