The 'Where Have You Been' singer uploaded the photograph to her account after a fan asked why she had "been quiet all day".
Rihanna did not add any comments or captions to the photograph.
She later uploaded another picture of a plane, saying: "My ride home NY days LA nights #itwuzreal."
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 'white powder' 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.
