It was not Usher’s finest moment.

Forced to cancel his Wednesday concert at Berlin’s 02 Arena at the last minute due to illness, the “OMG” singer, 32, rescheduled the show for the next night and promised his fans, via Twitter, “the show that you all properly deserve.”

Unfortunately, his illness didn’t clear up and Usher lip-synched his first two songs and danced poorly to them, according to local tabloid B.Z. Fans on the edge of the stage reportedly started complaining. Boos were also heard.

Usher himself expressed his disappointment about the situation. “I deeply regret having to reschedule the shows,” he said in a statement released Friday. “I am truly sorry for any inconvenience I have caused my fans. My fans are the best in the world and I am looking forward to getting better so that I can give them the show they deserve.”
