She tried to hire a bunch of people out from under me” (via Glamour).

Perry then appeared in the video for Swift’s song “U Need to Calm Down.”

Perry took things one step further, finding a way to differentiate between the two locks of hair.

“I put little bows on them individually and put them in my purse.

According to Cyrus, Perry even wrote her breakthrough hit “I Kissed A Girl” about her.
