Rose took to Threads on Sunday to accuse the pop star of assaulting her at a nightclub nearly 20 years ago.

“Katy Perry sexual assaulted me at spice market nightclub in Melbourne,” the Aussie actress wrote in response to a comment about the singer being at Coachella. “I was only in my early 20s. I’m now 40. It has taken almost 2 decades to say this publicly … I told the story publicly but changed it to be a ‘funny little drunk story’ because I didn’t know how else to handle it. Later she agreed to help me get my US visa. So I kept it a secret. But I DID tell yall she wasn’t a good person. Instead I got attacked by.. everyone.”

Rose added, without elaborating, “Just left the police station.”

Rose’s comments were kicked off by Perry attending Coachella over the weekend along with her partner, Justin Trudeau.

Rose had her breakout role in the Netflix series Orange Is the New Black and also had roles in 2018 hit The Meg and 2017’s John Wick: Chapter 2.
