After suffering a mild concussion by somehow crashing into a glass wall or window backstage in Paris on Thursday, Bieber says the injury has affected the right side of his face.
"I can't move my eyebrow," Bieber, 18, says in a Viddy.com video posted Friday. "It's the weirdest thing, some weird stuff going on."
The "Boyfriend" singer was able to continue performing after the mishap, though as he was walking to his dressing room he passed out for about 15 seconds.
In the video, he sums up the experience this way: "I got into a fight with a glass window."
