Teen sensation Justin Bieber bounced back from an awkward encounter with a glass wall by performing to fans from the balcony of his record label's headquarters in Paris yesterday (June 1).

The 18-year-old hitmaker suffered a concussion on May 31 after running head first into a glass wall backstage at one of his concerts, but treated his French followers to an impromptu rendition of 'Baby', 'One Time' and 'Boyfriend' from Universal's balcony in the Latin Quarter.

Tweeting about the exciting event, which was incredibly well-received, he wrote: "Loved singing with all of you #WithDanKanter - just like old times. #AlwaysKidrauhl"

Dan Kanter, Bieber's guitarist and music director, added: "What an amazing singalong off the balcony in Paris again w/ JB. We should do that every 2 years! Memories for life."
