This no doubt had Usher fans in Germany saying, oh oh, oh my gosh.
The soulful R&B singer was forced to delay his Berlin concert on Wednesday and reschedule it for tonight after taking ill.
The last-minute cancellation came after the Grammy winner was diagnosed with a paranasal sinus infection.
But despite feeling under the weather, Usher made sure to take the time to tweet his apologies to ticket holders.
"I am truly sorry to all my fans in Berlin who were inconvenienced by tonight's postponement of the show," he wrote. "I was ill and felt that I would not have been able to give the show that you all properly deserve. The show is rescheduled for Thur, Jan 13@ the O2 World. I look forward to giving Berliners a great show!"
That is, as long as his fans watch their step.
