Bieber fever hit Birmingham last night as the teen idol kicked off his world tour.
Canadian pop idol Justin Bieber, 17, performed to thousands of screaming fans - predominantly teenage girls - during the sell-out concert.
And in what appeared to be a dream combination for tweens everywhere - his support act was latest pop sensation Willow Smith.

He broke hearts when he chose a girl from the audience to sing One Less Lonely Girl.
