In an interview Monday morning with Today, Perry said she was weeping after she was asked to headline the halftime show. And yes, she'd like to admit right now, she's pretty nervous about the upcoming performance, which follows Bruno Mars' much-talked about performance last year.

"Can I be human and say yes, I'll be nervous?" the pop star said with a smile, before explaining she's going to "recycle those nerves and make them adrenaline."

Perry has a lot of big surprises planned for the Super Bowl XLIX halftime show in Arizona, saying people should be excited for all her "entrances and exits."
