Usher Sick; Delays German Show

Representatives for R&B star Usher say his European tour opening concert in Berlin has been delayed by a day due to illness.

Usher apologized to his fans in a press release announcing the decision to push back the kickoff of his European tour by a day.

The singer says he didn't "feel that I could put on the show that my fans deserve."

He will play Berlin's O2 World arena on Thursday.

Berlin is the first stop on the Texas-born singer's European tour that follows the release of his sixth album "Raymond v. Raymond."
