During Kanye West’s concert in Los Angeles on Tuesday, Katy Perry recorded a video of herself jamming along to the rapper’s song, “Famous” — but only the part with that infamous lyric about Taylor Swift.

“I feel like me and Taylor might still have sex,” West raps while Perry’s eyes grow wide and she brings the camera close to her face. “Why? I made that bitch famous.”

Both pop stars have a history of knocking each other through social media and interviews. (Swift insinuated in a Rolling Stone interview that “Bad Blood” was about Perry; when asked if they would ever collaborate, Perry tweeted at a fan, “If she says sorry, sure!” in September.)
