Usher has had to delay the opening night of his European tour in Berlin because of illness.
The US R&B star apologised to his fans in a press release announcing the decision to push back the kick-off of his European stint by a day.
The singer says he didn't "feel that I could put on the show that my fans deserve".
He is now due to play Berlin's O2 World arena tonight (January 13).
Berlin is the first stop on the Texas-born singer's European tour that follows the release of his sixth album Raymond v Raymond.
