suffered a mild concussion Thursday after he ran into a glass wall backstage at a concert in Paris.
Bieber, 18, told TMZ.com
that he was disoriented after hitting the glass, only to return to the stage to finish his set.
But later, as the "Boyfriend" singer
was walking to his dressing room, he passed out for about 15 seconds, TMZ reports.
Immediately after the show, Bieber addressed the mishap, Tweeting
: "im fine. just smacked my head and needed some water. all good."
Doctors said Bieber suffered a mild concussion, but is expected to make a full recovery.
Bieber's manager, Scooter Braun, Tweeted
: "jb is gonna be fine. things happen. he is a trooper. canadian hockey player. tough kid. no issue."
And the singer himself maintained a sense of humor about it, addressing a similar incident in 2010, where he ran into a revolving door.
Bieber Tweeted: "i will see u again Glass. I will have my revenge. BIEBER vs GLASS. MGM LAS VEGAS 2013. lol. #GottaLaughAtYourself."
