“#HackersGonnaHate” read the first tweet from the hacked Katy Perry account. A shout-out to rival Taylor Swift was also found.

A warning to the 89 million people who followed Katy Perry on Twitter, her account was hacked late Monday so disregard her recent posts. The singer-songwriter who boasts the biggest following of any Twitter user appeared to have sent several homophobic and racist messages before sending a link to an unreleased song on Soundcloud called Witness.

One message included a shout-out to rumored rival Taylor Swift. It has been alleged that Swift’s song Bad Blood is about her rocky relationship with Perry. On Monday, Perry’s hacked account posted a tweet saying “Miss u baby @taylorswift13”.

The hacked tweets have been deleted from the account – though the singer has yet to address the incident.

An entertainment news site was able to grab a screenshot of the tweets.

Some fans speculate that the Twitter user @Sw4ylol was to blame since Perry’s hacked account posted a tweet asking people to follow the user. @Sw4ylol’s first tweet on his/her account is “Who TF is Katy Perry”.

Who TF is Katy Perry
