Doctors instructs Rihanna to party less

London: Singer Rihanna has been ordered by doctors to curb her partying lifestyle after falling ill.

The 23-year-old was forced to pull out of a show in Sweden Oct 31, after being hospitalised with influenza, and her medical team are concerned she is going out too much while on tour. "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," contactmusic.com quoted a source as saying. "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," the source added. IANS
