'Exhausted' Rihanna cancels show
Rihanna has been forced to cancel a show in Sweden due to exhaustion for a second time this week.
The singer felt ill ahead of her concert in Stockholm last night and decided, in consultation with a doctor, to cancel the show about an hour before she was to go on stage.
Live Nation spokesman Kristofer Akesson said Rihanna "is exhausted and doesn't feel well".
Rihanna called off a concert in Malmo in southern Sweden on Monday, but was able to perform the following night in Stockholm.
Organisers are trying to arrange new dates for the shows.
