Just when we finally got used to Rihanna's red-hot curls, she's switched it up on us again. Snaps show off Rhianna's long red hair debuting at a Sirius radio event, where Ms. Umbrella showed off a sleek black number that had us doing a double take. We're kind of digging the Cher look, but it seems to lack the usual edge that we know and love RiRi to rock. Plus, there's nothing inspirational about this 'do. What d'ya think, ladies? Is Rihanna's hairstyle super sleek or RiRi circa 2005? (BellaSugar)
