POP sensation Justin Bieber caused chaos outside the X Factor studios yesterday as a girl fainted while waiting for her idol.

The Canadian singer, 16, was greeted by hordes of teenaged fans.

They braved freezing temperatures to see him arrive for his performance on the ITV1 show last night alongside Pussycat Doll Nicole Scherzinger, 32, and boyband The Wanted.
