I can't help but think hip-hop all-star Rihanna would be diagnosed with some form of premature senility if she visited a good doctor. Sure, most famous rappers are naturally coo-coo for Cocoa Puffs, but when someone like Rihanna is tweeting prayers to the dude who once turned her into Rocky Balboa in hopes that his probation hearing goes well, you have to think this woman is a special kind of crazy. The kind that drives everyone else up a wall, even though we should just take a deep breath and relax. At least when she's not opening her arms to domestic abuse, she's up on stage opening her legs to thousands of fans, without pants on. Rihanna put on quite a show at the MGM Grand Garden Arena for the iHeartRadio Music Festival, wearing a sparkly Nathan Scott jersey and just about nothing else. If only those photographers would've gotten a tad closer to the stage, we'd find out, but instead we get the PG-13 version of the whole outfit. It's really too bad that such a seemingly confident and sexy artist is also so morally f*cked up. Anyway, enjoy Rihanna's shiny ass.
