Is the Roc Nation superstar slowly becoming burned out? Millions of fans wondered that very sentiment after Rihanna tweeted a photo of what appeared to be her arm hooked up to an IV drip. Days after the "Umbrella" star was a no-show for her Saturday Night Live rehearsal, Rihanna managed to make her live appearance and perform up to par. The star was treated for "exhaustion and dehydration," which could explain why critics and concerned parties all have been pleading with the musical ingenue to slow down.

Reportedly, Rihanna was released after a short stay and was cleared to fly home to Los Angeles on Wednesday afternoon. Brewing underneath all the elaborate outfits and crazy photos, people are worrying that the uninhibited 24-year-old might be getting more and more out of control. With her recent nearly-nude Twitter photo gala, bizarre fashion choices, and public smoking sessions, many believe that RiRi is crying out for attention. "She's been drinking almost every day and talking about smoking weed a lot, too. Everyone is telling her to slow down and think about therapy, or even rehab," said a source to RadarOnline.
