Katy Perry‘s Twitter account was hacked on Tuesday morning. The hacker tweeted a series of tweets from Perry’s account to her 89.1 million followers, including one directed to Taylor Swift.

Taylor Swift, 26, has been feuding with the “Fireworks” singer for some time now. Swift’s hit song, “Bad Blood,” is rumored to be about her relationship with Perry, 31.

“Miss u baby @taylorswift13,” the hacker wrote from Perry’s account.

One Twitter user screen-shotted the tweets before Perry regained control of her account and deleted them.

Many fans believe a particular Twitter user was the culprit for this hack but nothing has been confirmed.

Sw4ylol indirectly denied hacking Perry’s account by tweeting from his account that he doesn’t know who Katy Perry is.

Sw4ylol then tweeted another tweet with a link to a SoundCloud track called, “Witness 1.3,” which was rumored to be Perry’s new song. The tweet was taken down and replaced with another tweet of a screenshot of a letter from SoundCloud saying the track was removed due to a copyright claim made directly by Universal Music Group.

Since regaining control of her account, Perry and her reps have not commented on the hack.

Perry has the most Twitter followers in the world, with Justin Bieber ranking second with the most followers at 82.3 million followers.
