Rihanna was forced to cancel a second show in Sweden last night (02.11.11).
The 'We Found Love' singer was due to perform in the country's capital city Stockholm but a doctor deemed her unfit to perform an hour before stage time, as she had a bad case of flu.
A statement from concert promoters Live Nation said: "Unfortunately, we need to report that the concert with Rihanna tonight at the Ericsson Globe [venue] has been cancelled due to illness.
"Rihanna is exhausted and sick. Unfortunately we have once again been forced to make a difficult decision at the last minute."
The 23-year-old pop star was later transported from the hospital to her hotel, accompanied by two minders, wrapped in a big grey wool coat and looking withdrawn.
On Monday (31.10.11) Rihanna had to cancel another date in her 'Loud Tour' in Malmo after being hospitalized and placed on a drip. She posted a picture of the tube feeding into her arm on twitter with a caption reading "Sorry, Malmo!"
She also later released a statement to apologize to fans, which read: "I am sorry to everyone who was coming out to my show in Malmo, Sweden. I was so excited to perform for you all.
"It would have been a great time ... so much better than being sick with the flu, ugh! I'm really disappointed I couldn't be there."
Earlier this week, it was reported doctors had told Rihanna to curb her partying to stay healthy on the road.
