*Usher has postponed two more concert dates on his European tour after a doctor prescribed bed rest to fight off a respiratory illness.
The singer already pushed back a planned gig at the O2 World in Berlin, Germany on Wednesday after falling ill earlier this week. He returned to the stage for the rescheduled concert on Thursday, but had to cut the gig short after just a handful of songs.
Usher lip-synched his first two numbers 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. In response, he reportedly lowered his head and stood silently on the stage for about four minutes before leaving altogether. The stage lights came on and fans were told the star was too sick to continue the show.
