bieberAUcanc.jpg Justin Bieber was supposed to perform for thousands of fans on the Sunrise show in Sydney, Australia this morning, but local police cancelled the performance on the outdoor stage due to "crowd concerns and safety."

Thousands of fans showed up to the studio, many of whom camped out overnight, and the Bieber lovers forced a crowd surge at 2am, resulting in at least a dozen teenage girls requiring medical attention, according to the New Zealand Herald.

After the incident Justin tweeted, “I am just as disappointed as everyone else with the news from this morning. I want to sing for my fans," but he did end up performing his hit “Baby” inside the studio. Maybe watching Justin perform from TV is the safest way to go - we're hearing one teenage fan broke her leg in the crowd chaos!
