Doctors have apparently expressed fears for her well being after she fell ill with laryngitis and was forced to axe two dates on her Diamonds World Tour.
The 25-year-old has been told that she won't be able to sustain the level she's currently operating at if she doesn't ease up on the partying front, reported Sun Online.
"Rihanna's illness was so severe that doctors warned it could take months for her to fully recover - there were worries that she'd have to cancel her entire tour. They've told her that she needs to make some serious lifestyle changes, or risk this happening again.
