Katy Perry has made it clear that she will always protect herself and her reputation against anyone who tries to challenge her.
In an interview with Billboard magazine ahead of her Half-Time Superbowl show performance later today, she said: "If somebody is trying to defame my character, you’re going to hear about it."
Taylor Swift described a fellow female musician last year as her "straight-up enemy" who tried to "sabotage [Swift’s] entire arena tour".
The next day Perry tweeted, "Watch out for the Regina George [a Mean Girls reference] in sheep’s clothing".
