Rihanna has posted a picture of her hooked up to a drip last night. The twitpic was in response to a fan who tweeted: "@rihanna What da fuxx good?! You been quiet all day."

No captions or comments were added to the picture - but fans responded on her Twitter page, asking about what happened and that they hope she gets better soon.

But reports say that the singer was rushed to the hospital for exhaustion and dehydration after partying at the Met Ball in New York on Monday night.

It has just been confirmed by Fox that the Umbrella singer will perform at the grand finale of American Idol this month. She will perform her latest single "Where Have You Been" on May 23.

Latest rumors about Rihanna is that the songstress is "freaking out" over claims that her ex Chris Brown will be releasing a tell-all book which will reveal their romance between the pair. Brown is expected to write about the sexts they sent to each other and the argument the two had - which resulted with Rihanna having a bruised face and eyes. Chris Brown had pled guilty to assault and Rihanna has since reconciled with him.

Though the two have not been together since 2009, rumors suggest that they might be seeing each other. They have been photographed cozying up to each other at Rihanna's Valentine's Day party.

Rihanna opened up about her reconciliation with Chris Brown in an interview for the may issue of Elle Magazine.
"The bottom line is that everyone thinks differently. It's very hard for me to accept, but I get it. People end up wasting their time on the blogs or whatever, ranting away, and that's all right. Because tomorrow I'm still going to be the same person. I'm still going to do what I want to do," she said of the reconciliation.
