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

The singer told reporters at a press conference Thursday that her performance Sunday will include "a lion and sharks."

"It's going to be wild out there," Perry teased.

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. Perry said her performance will also include an "old school" female singer whom she declined to identify but said would be instantly familiar from the get-go.

"When you hear the first ring of the chord, I think jaws will drop and faces will melt," she said.

She said the audience can expect to hear two of her hits, "Roar" and "Fireworks." Her performance would be a visual feast in the tradition of Madonna and will celebrate "female empowerment," she said.

Perry was playful with reporters, indulging one who wanted to take a selfie photo with her and shouting at a pair of puppets brought by a Mexican television crew.

While she was enthusiastic about talking about her show, when the topic turned to her love life, Perry channeled Seattle Seahawks running back Marshawn Lynch, who's gained fame for refusing to answer reporters' questions.

"I'm just here so I don't get fined," Perry said with a serious face. In true Lynch fashion, she repeated the line again.
