R&B star Usher pulled out of a concert in Berlin, Germany on Wednesday night (12Jan11), after falling ill with a sinus infection.
The Yeah! hitmaker was scheduled to perform at the city's O2 World venue, but scrapped the gig at the last minute after he was diagnosed with a paranasal sinus infection, according to local reports.
Usher has rescheduled the show for Thursday (13Jan11) and taken to his Twitter.com page to apologise to fans.
In a series of posts on the microblogging site, the star writes, "I am truly sorry to all my fans in Berlin who were inconvenienced by tonight's postponement of the show.
"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!"
