Not a fan then Ruby, no?
Today, Katy Perry released the third song off her new studio album Witness.
It's called Swish Swish and features Nicki Minaj. Ruby Rose has had her say on Twitter, as the track is quite shady and allegedly alludes to Katy's feud with Taylor Swift.
There's no direct reference to the tiff, but many fans have speculated that Katy is telling Taylor to 'Swish Swish Bish.'
Ruby Rose has now lashed out in defense of her best pal Taylor.
"Purposeful poop" to "bomb a petit" to a sloppy mess of writing over the top of Funkagenda..stop trying to make 'Wit..I mean "fetch" happen.— Ruby Rose (@RubyRose) May 19, 2017
I just think with everything going on in the world to go from rebranding as political activist only to ditch it and go low.. is.. a bummer.— Ruby Rose (@RubyRose) May 19, 2017
Ruby also tweeted to say 'You are her fans you should buy all her songs so the songs will finally chart.'
