London: Singer Justin Bieber shocked his fans by flashing his innerwear during a concert.

The "Baby" hitmaker was performing at a venue in Carson, California during the weekend when his low-slung jeans slipped down his thighs, revealing his white boxer shorts, reports contactmusic.com. The 18-year-old was then seen struggling with his belt before continuing with the show. IANS
