Ruby Rose Slams 'Bully' Katy Perry's New Music, Defends Pal Taylor Swift

Rose claims that Perry is a 'bully' and mocked her new music in a series of shady tweets.

Shade alert! Ruby Rose took to Twitter on Thursday to make some not-so-veiled jabs at Katy Perry’s new music.

“’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,” Rose wrote, referencing Perry’s new album, Witness.

The album is due out on June 9, and Perry has already released singles “Chained to the Rhythm,” “Bon Appetit,” and most recently, “Swish Swish,” which features rapper Nicki Minaj.

Perry's lyrics to "Swish Swish" do appear to be slamming somebody, though she never mentions her frenemy -- and Rose's pal -- Taylor Swift. It could be noted, however, that "swish" isn't so far off from Swift. 

"From a selfish or a sheep/ Don't you come for me/ No, not today/ You're calculated/ I got your number," the 32-year-old pop star sings. "'Cause you're a joker/ And I'm a courtside killer queen/ And you will kiss the ring/ You best believe."

"So keep calm, honey, I'ma stick around/ For more than a minute, get used to it," she continues crooning. "Funny my name keeps comin' outcho mouth/ 'Cause I stay winning."

When a fan noted that Rose better not be insulting Minaj's involvement in the song, the 31-year-old actress and model reacted, “Not gonna lie, Nicki is great on it and basically the only part that doesn’t sound a mess.” She later added, “I toured with Nicki. She was very nice. Very funny and very talented.”

But Rose’s rant against Perry didn’t end there. She went on to note her involvement in Hillary Clinton’s 2016 presidential campaign, writing, “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.”

The Orange Is the New Black star added, “I’ve always stood up for the people I love and against things I think are cheap or mean spirited. That’s not new. You have to follow your [heart].”

When someone accused Rose of being a hypocrite, referencing Swift’s song “Bad Blood,” which is rumored to be about Perry, she had a quick response.

“Wasn’t around sweetheart but my bully experiences came from one of the people involved in that song and it’s obviously not T,” she wrote.

As Perry’s fans continued to slam Rose for her comments, she replied, “You are her fans you should buy all her songs so the songs will finally chart. If as many as tweeted me bought her last 3 .. they’d be hits.”

Some Swift fans also went on to praise other members of the GRAMMY winner’s squad, specifically Selena Gomez’s new single, “Bad Liar.”

“So good! And Haim!” Rose added, referencing more of the celebrity friend group. “And Lorde.”

Swift has been out of the spotlight recently as she is reportedly preparing to release new music. Meanwhile, in addition to the upcoming Witness, Perry has also announced that she will be a judge on the ABC reboot of American Idol.

Fans of Swift and Perry called shade when it was announced that the “Firework” singer would be collaborating with Swift’s DJ ex, Calvin Harris, for some of her new music. But Perry has denied that any of her songs will call out Swift specifically.
"I think [my new album is] a very empowered record,” she told Entertainment Weekly. “There is no one thing that’s calling out any one person."
