Usher was supposed to be performing in Rotterdam, Holland tonight but the show's been canceled...
This is the second and a half show Ush has canceled on his European tour including the opening night.
Just last night video surfaced of Usher being booed off stage in Berlin, Germany after a listless set of just four and half songs at an ill fated make-up show for the opening night cancellation.
According to reports Usher is suffering from a sinus infection.
