Rihanna is no stranger to causing controversy, but this week she has found herself at the centre of a new scandal.
The We Found Love singer got herself into hot water, after posting a picture of herself to photo sharing website, Instagram, 'cutting up' a white powdered substance.
She posted two photographs of herself sat on a man's shoulders and one close-up of the substance on his head.
The image was from when the 24-year-old star was at American music festival, Coachella, where she also performed.
It was posted along with the caption:
"Memories don't live like people do #coachella."
Earlier this year, the Bajan singer faced questions over another snap which showed her on holiday in Hawaii, smoking what looked like marijuana.
Rihanna is currently promoting her new movie, Battleship, which is in cinemas now.
