Katy Perry says her Super Bowl halftime performance will make you "Roar" -- with animals.

The singer -- wearing a dress patterned with footballs -- told reporters at a press conference Thursday that her performance Sunday will include "a lion and sharks."

Perry, 30, said she feels blessed to perform on the Super Bowl stage "at such a young age." She said she enjoyed past Super Bowl performances from Beyonce and Madonna, and what she adds "is some lightheartedness."

Lenny Kravitz will join the pop star at the University of Phoenix Stadium in Arizona, where the New England Patriots will take on the Seattle Seahawks. Perry said her performance will also include an "old school" female singer.

When asked if Perry had been checking out football players this week, she imitated Seattle Seahawks running back Marshawn Lynch, saying: "I'm just here so I don't get fined."

In case you needed further proof Perry is excited for Sunday, look no further than her Instagram. "Even my tippy toes are ready," she wrote, captioning a pic of a football-inspired pedicure.
