Rihanna Isn’t Taking Any Chances These Days (PHOTOS)

Gee, does Rihanna seem a little…defensive in this pic?

Behold, the “Russian Roulette” songbird practicing for the Pepsi Super Bowl Fan Jam concert, brandishing a microphone stand that seems to double as a set of brass knuckles. And maybe a scimitar too.

Does she have a grenade hidden under her hat as well? Can’t say as we’d blame her, after all that she’s been through.
