{blackbabes} Rihanna Hospitalized With Flu in Sweden, Cancels Concert

This is turning out to be not such a happy Halloween for Rihanna (and her Swedish fans).

The "We Found Love" singer was forced to cancel her concert at the Malmo Arena in Sweden tonight after she came down with a bad case of the flu.

"Sorry Malmo!!! #LOUDtour," Rihanna tweeted Monday, along with a photo of herself hooked up to an IV drip in a hospital in Sweden.

"I am sorry to everyone who was coming out to my show in Malmo, Sweden," Rihanna said in a statement. "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."

"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."

According to the singer's website, Live Nation is hoping to reschedule the performance with details to follow in the next few days.
