Rihanna has been ordered by doctors to curb her partying lifestyle.
The Cheers (Drink to That) singer was forced to pull out of a show in Malmo, Sweden, on Monday after being hospitalised with a bout of flu, and her medical team are concerned she is going out too much while on tour.
A source told The Sun newspaper: "Rihanna is running on empty but she's still been going out drinking and living it up.
"She doesn't have any down time where she can completely relax. She spends most of her time in the studio, on stage or in clubs. Doctors are worried she's overdoing it.
"She needs to take some time off. Otherwise she'll be vulnerable to more illness."
