Katy Perry & Rihanna Super Bowl Halftime Show 2015 Surprise? John Mayer's Ex Hypes 'Female Empowerment' Amid Lenny Kravitz Performance Announcement [WATCH]

Pop princess Katy Perry will perform during this year's highly-anticipated Super Bowl halftime show. According to the "Roar" songstress, fans can expect several onstage shockers... maybe even a surprise appearance by hip-hop BFF, Rihanna?

Girl power!

In a recent interview with Entertainment Tonight, John Mayer's ex teases viewers with this statement:

"I have a couple of tricks up my sleeve, but I can't tell you everything. I'm gonna let people just think about it..."

Thankfully, it's already been confirmed that rocker Lenny Kravitz will also perform during the annual sporting event. But what about RiRi? When Perry's pressed for more info, she simply responds:

 "Let's just say, female empowerment."

Come on! So many options... Nicki Minaj, Lady Gaga, Taylor Swift (ha, probably not).

So, the "Dark Horse" crooner must be pretty excited, right?

"I think my moment will be when I'm finished. I think the adrenaline is going to give me these wings of sorts, but afterwards it will just be like, 'ahhhh'... And I'll have a pizza on standby, okay?"

Typical Perry.

The Superbowl kicks-off on Sunday, February 1st. The playoffs continue this weekend with the Green Bay Packers taking on the Seattle Seahawks and the Indianapolis Colts battling against the New England Patriots. Any predictions, MstarsNews fans? But who's more pumped for the awesome halftime gig!?
