Justin Bieber Suffers Concussion After Running Into Wall

Sounds like Justin Bieber was feeling a little too tough after those boxing lessons with Mike Tyson.

In his most recent stop during his European promotional tour, Justin Bieber had a bit of a mishap backstage. And by "bit of a mishap," I mean he "ran his head straight into a glass wall."

Bieber was on a stop in Norway when the incident occurred, performing a free concert. Apparently he didn't see the wall backstage and fell into it, hitting his head hard enough to get a little dizzy. He went out and performed his final song, then reportedly passed out backstage for about 15 seconds.

Don't worry, Bieber fans: he seems to be doing just fine, and was told by his doctors that he just needed to take it easy for a bit. The ones you should be worry about were the girls at the concert: Bieber was forced to tweet out a message imporing everyone to cooperate with the police after nearly 50 girls were injured and 14 of them hospitalized thanks to the unruly crowd.

Bieber is currently mired in some other trouble that might cause him a headache: prosecutors are taking up a case that accuses Bieber of battery against a photographer.
