There is a rumor flying around that Katy Perry and Taylor Swift feud has a sequel this 2015!

According to a news outlet, "Dark Horse" singer Perry has a plan to bash "Shake It Off" singer at Superbowl performance.

This rumor began from a Hollywood Life's source. She or he said, "Katy is in complete rehearsal mode for her Super Bowl performance, she wants to make it feel like a complete party and something that will be remembered forever."

"She wants to make a statement with her performance and show that she is the biggest female act in the world and she wants to show that to everyone including Taylor, who she has a feud with. In Katy's eyes, no one can compete on her level," the source added.

"Katy will be doing something on stage during her performance that will be directed towards Taylor. She is working on it to be a visual or a lyric related jab."

Blast from the past, the root of the two singers' feud has something to do with the "stealing of backup dancers" issue, according to Jezebel.

After that incident, Rolling Stone conducted an interivew with T.Swift where the singer gave a hint about the meaning of "Bad Blood." Some said that this song is about her feud on Perry. Swift told Rolling Stone, "For years, I was never sure if we were friends or not."

Then she continued, "She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?'" Then last year, the other star crossed a line. "She did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy! It had to do with business. She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me. And I'm surprisingly non-confrontational - you would not believe how much I hate conflict. So now I have to avoid her. It's awkward, and I don't like it."

After this issue surfaced online, "Roar" singer seemed to post tweets with double meaning such as: "Watch out for the Regina George in sheep's clothing..."

Do you think that this cat fight will rise again this year?
