Justin Bieber has assured French fans he's fine after blacking out during a concert in Paris on Thursday night (31May12).
The Baby hitmaker, who is performing a series of mini-gigs as he travels through Europe promoting his upcoming album Believe, ran into a pane of glass backstage midway through the gig in the French capital and hurt his head.
The clumsy 18 year old eventually returned to the stage to finish his set, but blacked out for 15 seconds in his dressing room after the concert.
Taking to his Twitter.com page after the gig, Bieber told fans, "thanks for the love... im fine. just smacked my head and needed some water. all good. im Canadian. we are tough. its all good. just gotta take it easy the rest of the night."
He has since told Tmz.com, "I was performing and I was going offstage... and there's a glass wall behind me but there's a railing behind the glass and so I went to reach for the railing and I hit my head on the glass... and then after that it really hurt and I felt a little light-headed, but my adrenalin pushed me through it and I performed the last song.
"After that I went offstage and I immediately felt really weak and then I was walking down the stairs and I passed out for, like, 15 seconds and I was unresponsive... I opened my eyes and I saw the doctor and he told me I had, like, a concussion.
"I feel good. I have a little bit of a headache."
Bieber's mini-tour has been blighted by injury - following his show in Norway on Wednesday night (30May12) the star revealed he had injured his hip.
