The gloves are coming off! It's been rumored for weeks now that Katy Perry was going to dis Taylor Swift during her Super Bowl Halftime performance and reportedly the 30-year-old "Roar" singer just issued a warning to her sworn "enemy."

In the new issue of Billboard magazine, Perry briefly spoke about her rumored plan and it sounds like Swifties might want to avoid watching the halftime show.

"If somebody is trying to defame my character, you're going to hear about it," she said.

News of a Perry/Swift feud surfaced last month after Swift told Rolling Stone magazine that her song "Bad Blood" from her album "1989" was about another female artist she considered a straight-up enemy.

Perry responded to the interview by taking a jab at the "Shake It Off" singer with a reference to the movie "Mean Girls."

"Watch out for the Regina George in sheep's clothing," she wrote.

Perry also talked about her feud and Halftime plans during an interview with "Entertainment Tonight" when Kevin Frazier asked her if she was going to sing about a "certain someone."

"I don't know where you heard that," she said. "I think the speculation is very fun. And I don't usually like speculation, but I'm like 'Hey!' It's like bringing everybody into the conversation, you know, and on February 1, you'll see what's actually gonna go down."

Rumors and cat-fighting aside, Perry admitted to Billboard that she is nervous about her halftime show.

"Everyone has been asking me if I'm going to be nervous before the halftime show," she told the magazine. "I'm like, I'm f**king human. This is the biggest event of my career."

NBC will air a livestream of the big game (Seahawks vs. Patriots) and the halftime show on their NBC Sports website. You can check it out here on Sunday, Feb. 1.
