Rihanna Sparks Concerns Over Health With IV Photo

Rihanna sparked concern among her fans last night when she responded to a fan questioning her day-long Twitter silence (the pop star is avid in her use of the medium) with an Instagram photo of an IV in her arm.

"What da f**x good?! You been quiet all day," the fan observed.

The pic comes just days after Rihanna reportedly opted out of final rehearsals for her "Saturday Night Live" appearance this weekend, saying she was sick. That same day, she tweeted that she wasn't feeling well.

But fan's can rest easy that she is on her way home to LA – hopefully to get some rest. Early this morning, Rihanna tweeted a photo of herself getting ready to board a private jet from New York to Los Angeles. "My ride home NY days LA nights," she tweeted, adding the hashtag, "#itwuzreal."
