Rihanna Rihanna seems to be very run down and has been warned by doctors to take some time out or she will get very ill. We think our mums would say she has been burning the candle at both ends... working very hard. But partying very hard too. We heard that last weekend she had to cancel a gig in Sweden because she has the flu. Doctors are saying that if she doesn?t calm down and get some rest, then the flu could turn very nasty. A source said: "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." Rihanna never fails to party whilst on tour. It was only last month when she was in the UK that she was nearly kicked out of a strip bar for repeatedly touching the dancers, after enjoying a night out there. As well as partying after the shows, on the rare nights that she didn?t go out, she was staying up and working on her new album until 8am. Fellow stars have been worried about her. Jay Z and USA X Factor judge LA Reid have both sent flowers and wished her a speedy recovery. So maybe less of the tequila hey Rih!
