As reported by AOL Music, after being hospitalized and put on health watch in 2011, Rihanna has sparked speculation that she has faced yet another medical scare. The singer tweeted a photo of her arm hooked up to an IV on Tuesday (May 8), following a long night of partying with her fellow celebs at The Met Gala in New York (May 7).

When one of her Twitter followers asked Rihanna why she was being so quiet on her normally very active Twitter page, Ri responded with a photo of her arm -- and signature claws -- attached to an intravenous tube.

The photo comes just days after RiRi revealed she was feeling sick before and after her performance on "Saturday Night Live." See the image after the jump!

Ri posted a very similar image after she was hospitalized in Sweden during a bout with the flu late last year. That episode was followed by orders from her doctors to cut way back on her hard partying ways. A month later, Ri was put on health watch following a backstage meltdown. Of course, we have tons of evidence that she's no longer adhering to the doctors' orders -- if she ever did. Most recently a certain well-documented strip club adventure comes to mind!

Do you think the IV -- commonly used to combat dehydration -- is a sign that Ri was out too late partying?
