Justin Bieber Got Mobbed On The Street When He Rode Around Perth On A Motorbike

Bieber fever is alive and well.

Justin Bieber has kicked off the Aussie leg of his Purpose world tour and the Beliebers are watching his every move.

In Perth on Thursday, the Canadian pop star took a spin around the city on a motorbike but was predictably tailed by a mob of fans. Footage online shows young fans, armed with cameras and phones, surrounding Bieber on the road.

The women in the car are concerned for his safety, calling out "leave him alone" to the squealing crowd.

Bieber is gearing up for his second concert in Melbourne on Friday, before touring to Brisbane and Sydney. The opening night didn't exactly get rave reviews, but we don't think his adoring fans will notice anything beyond the sound of their own squeals.
