'Roar' singer Katy threw an American football into the audience as she stood on stage at the Super Bowl XLIV press conference in Phoenix on Thursday (29 January).
Katy, 30, donned a playful blue and orange top and skirt combo, which was covered with American football designs.
This weekend's showdown on Sunday 1 February, between the New England Patriots and the Seattle Seahawks, will see Katy perform during the halftime show.
Having already confirmed that Lenny Kravitz will be joining her on stage, Katy revealed at the conference that an "old school" female musician will also be on hand.
She said: "When you hear the first ring of the chord, I think jaws will drop and faces will melt."
Who on earth could it be?!
Katy, who said she's been closely overlooking every detail of the performance, added: "There is not a diamond on the shoe that has not gone past my eyes. I feel that in some ways it's a spiritual experience for me.
"I just hope that at the end of the day, over 100 million people are all smiling in unison."
