The "Roar" singer took to Instagram on Monday to show off her newly-painted nails, which feature football-inspired brown polish with a white cross-stitch pattern down the center of each one.
"Even my tippy toes are ready," she captioned the pic of her feet.
No word yet on if the pop star got a matching manicure ... but knowing Katy, we think she's going to have an outrageous sports-themed ensemble when she hits the stage for her halftime show on Sunday.
According to Billboard, the 29-year-old entertainer beat out Coldplay and Rihanna in the National Football League's decision. She'll reportedly hit the stage with Lenny Kravitz for the big performance.
Are you excited to see her perform? Sound off below!
