Katy Perry is planning to make a "jab" at Taylor Swift during her Super Bowl performance.
The 'Dark Horse' hitmaker will take to the stage for her halftime performance at the event next month and is reportedly ready to show that she is "the biggest female act in the world".
A source revealed to HollywoodLife.com: "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.
"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."
Meanwhile, the 30-year-old singer is believed to be keen to recruit Pharrell Williams, 41, so the pair can perform one of her tracks together.
A source previously shared: "Katy is a huge fan of Pharrell and knows that having him duet with her on one of her songs during her performance will make all the difference.
"Her people are already in early talks with people about setting it all up. He is tempted as he knows it will be an amazing, slick, professional show."
