Katy Perry is speaking out about her rumored feud with Taylor Swift.

As the 'Roar' singer gears up for her Super Bowl performance on Sunday, she talked to Billboard about the whole shebang -- and yes, when asked, she did also touch on the T. Swift drama.

"If somebody is trying to defame my character, you're going to hear about it," she said in regard to the supposed feud. Them's fighting words!

As we previously reported, Taylor's biting '1989' track, 'Bad Blood,' is believed to be about Katy Perry. (While she didn't name names, Taylor admitted to Rolling Stone that the song was about a fellow pop star who tried to sabotage her arena tour.) After the interview, Katy subtweeted, "Watch out for the Regina George in sheep's clothing." Since then, Katy is rumored to have a new song 'She's So Creepy,' which is supposedly about T. Swift. Could that be what the raven-haired singer is referring to in her Billboard interview?

Only time will tell -- and it looks like Katy Perry may be pretty vocal about it.
