Ever since Taylor Swift said that 1989 cut “Bad Blood” was about someone in the music industry and not an ex-boyfriend, rumors swirled that the pop star was referring to Katy Perry. But neither singer explicitly commented on the supposed feud until Monday night, when Perry went on The Late Show With James Corden and confirmed she did indeed have a rocky relationship with Swift.
“Honestly, it’s really like she started it and it’s time for her to finish it,” Perry said of the fight, which started over backing dancers. She later claimed to have tried to talk to Swift, but to no avail. “It was a full shutdown and then she writes a song about me, and I’m like, ‘Okay, cool, cool, cool, that’s how you want to deal with it? Karma!’” Perry said, before admitting that she would quash the beef with Swift if the 1989 singer reached out to talk.
It wasn’t always like this. In fact, the two began exchanging friendly tweets in 2009, just five years before “Bad Blood” came out. Ahead, check out a timeline of Swift and Perry’s falling out
Eight years ago, Swift paid Perry a compliment via Twitter. “Watching the Waking up in Vegas video,” she wrote. “I love Katy Perry. I think I’m going to hang her poster on my wall now.” Perry responded, “You’re as sweet as pie! Let’s write a song together about the subject we know best… for my new record. It’ll be brilliant.” (The proposed collaboration never happened.)
Between 2009 and 2014, the two publicly exchanged birthday wishes and tweets about cats, and Perry even stopped by Swift’s Fearless tour to perform “Hot N Cold.”
