Pop star Rihanna was reportedly rushed to the hospital early Wednesday morning following the Met Gala in New York. The star was treated for "exhaustion" and "dehydration," which have been known to be Hollywood-speak for something far more serious. The singer was reportedly released after a short stay and cleared to fly home to Los Angeles Wednesday afternoon. Rihanna had said she wasn't feeling well a few weeks ago, when she hosted Saturday Night Live, though others worry her partying might be getting out of control. Usually an active Twitter user, Rihanna didn’t post for much of Wednesday before tweeting out an image of her arm hooked up to an IV to her followers confirming she had been hospitalized.
