Katy Perry says Super Bowl performance will make you 'Roar'

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."

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.

Missy Elliot may be guest

A person familiar with the plans for Sunday's halftime show told The Associated Press on Thursday that Grammy winner Missy Elliott is slated to make a surprise appearance during Perry's performance.

The person spoke to the AP on condition of anonymity because Elliott's participation had not been announced by the NFL.

Elliott was featured on a remix of Perry's song "Last Friday Night (T.G.I.F.)" in 2011.

During her news conference Thursday, Perry hinted at Elliott's involvement in the Super Bowl act, which also will feature Lenny Kravitz.

Perry said the halftime show will include an "old school" female singer — but did not say who that would be.

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

Elliott is a multiplatinum rapper, singer and producer whose Grammy Awards from the early 2000s include Best Rap Solo Performance for "Get Ur Freak On," and Best Female Rap Solo Performance for "Work It" and "Scream a.k.a. Itchin'."

Other Super Bowl halftime shows have included unannounced performances, including by singer Usher and former Guns `N Roses guitarist Slash in 2011.
