PHOENIX (AP) - 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 Beyoncé 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 who 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.

Later Thursday, a person familiar with the plans for the halftime show told The Associated Press that the surprise guest is slated to be Grammy winner Missy Elliott, who was featured on a remix of Perry's song "Last Friday Night (T.G.I.F.)." The person spoke to the AP on condition of anonymity because Elliott's participation had not been announced by the NFL.

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

Perry said one element of the show is the unfurling of a giant screen that will go on the field for visual effects, and she'll also change her outfit several times.
