Comedy Central may have “roasted” James Franco last night in Culver City, but at the VMAs in Brooklyn, it was all about grills. Rihanna was decidedly understated this year—wearing cuffed jeans, an MC Lyte tee, a diamond-studded collar, and a tiny cross positioned between her two front teeth. And while this isn’t the first time that RiRi debuted some bedazzled dental work (wearing a much larger gold gun earlier in the month), this bite-sized version is something we can get on board with (especially when compared to Katy Perry’s over-the-top, rainbow, diamond-studded “ROAR” mouthpiece). With everyone from Madge to Queen Bey giving their pearly whites a serious gilt trip, we’re wondering if the mouth party will become as mainstream as the arm party? And an even bigger question, will Lara Stone or Georgia May Jagger fill their famous gaps with grills? Time (and teeth) shall tell.
