Poorly Usher cancels concerts

Usher's not a well man at the moment.

A sinus infection is badly hampering is his tour of northern Europe. The OMG signer was forced to pull out of a gig in Berlin on Wednesday and now tonight's gig in Rotterdam has been cancelled.

Usher has been tweeting apologies to his fans, "I am truly sorry to all my fans in Berlin." The gig did go ahead 24 hours later but reports say it was a brief appearance.

The Rotterdam gig has been rescheduled for the start of March.
