Some kidding aside, the kid does have a strange penchant for walking into glass — he's done it at least twice before.
Bieber apparently passed out for several scary seconds after charging head-first into a glass wall during his concert in Paris last night. A consummate professional, the bubblegum-popster returned to complete the set, despite being diagnosed with a concussion and feeling "lightheaded."
Bieber later laughed it off, telling TMZ, "I guess me and glass windows just don't work." He also assured fans via Twitter that he was fine, tweeting "just smacked my head and needed some water. all good."
