"Rihanna has posted a photograph on Twitter which appears to show her hooked up to a drip. The &amp;#039;Where Have You Been&amp;#039; singer uploaded the photograph to her account after a fan asked why she had &amp;quot;been quiet all day&amp;quot;.  Rihanna did not add any comments or captions to the photograph. She later uploaded another picture of a plane, saying: &amp;quot;My ride home NY days LA nights #itwuzreal.&amp;quot; Rihanna has recently caused controversy by posting photographs on her Instagram account, including one which appeared to show her handing money to a stripper and another which apparently saw her with some kind of &amp;#039;white powder&amp;#039; at Coachella.   Rihanna, who will perform during the upcoming American Idol grand finale, recently caused further controversy on her Twitter page when she joked that she could turn a straight woman bisexual. She also reportedly angered producers of Saturday Night Live before her recent performance when she allegedly sent her choreographer to the dress rehearsal in her place.
