Ri Ri showed up at the VMAs last night in a floor-length, body-hugging white dress and with a lot less hair on her melon (a drastic change from what she had during her Oprah tear-fest). Known for switching out her hairstyles as often as best friend Katy Perry trades up her boy toys (we're still holding out for the return of Baptiste Giabiconi), last night's MTV Moonman winner has found her most low-maintenance, Caesar Augustus–ish look yet.
