Taylor Swift's Pal Ruby Rose Slams Katy Perry's New Song 'Swish Swish' as a 'Sloppy Mess' (Audio)

"'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 tweeted one hour after Perry released the single.

"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," Rose posted on Twitter, followed by, "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 .. the'd be hits."

The dance song features Nicki Minaj, who Rose made sure to defend as being "the only part that doesn't sound like a mess."

Some of Perry's lyrics have fans wondering if "Swish Swish" is a response to Taylor Swift's "Bad Blood," which has been linked to the two singers' fallen friendship.

"She basically tried to sabotage an entire arena tour," Swift told Rolling Stone back in 2014. "She tried to hire a bunch of people out from under me."

Fans speculated Perry was the performer Swift would not mention by name because the two have had the same dancers work on their tours.

Minaj and Swift have also beefed in the past after Minaj took a dig at the "Shake It Off" singer after the 2015 MTV VMA nominations were announced.

Some of Perry's "Swish Swish" lyrics that are raising eyebrows include, "Don't you come for me / No, not today / you're calculated / I've got your number / Because you're a joke / and I'm a courtside killer queen."

Amid the speculation that "Swish Swish" and "Witness" were responses to Swift's "Bad Blood," Perry told Entertainment Weekly that "there is no one thing that's calling out any one person."

"It's really quite brave. Sonically, it's fun and dance-y and dark and light. It's all of these things. It definitely is a change," she said.

But Twitter's not buyin' it.
